To study the moldy condition of feed mixed with corn, soybean meal and bran at the ratio of 1:1:1 at the addition amount of 5% and 10% rapeseed oil, lard and mixed oil (rapeseed oil + lard) at 35 °C, 15% moisture concentration. Seven mixed feeds with the same quality were taken. Three respectively mixed with 5% of the rapeseed oil, lard and mixed oil (rapeseed oil + lard). Three respectively mixed with 10% of the rapeseed oil, lard and mixed oil (rapeseed oil + lard). One as the control sample. Put seven samples at 35 °C in the incubator, in 20, 40 d to determine the seven samples feed moisture, crude ash, crude protein, pH value, crude fat. The seven samples were tested with aflatoxin B1 and zearalenone test papers. The results showed that added 10% mixed oil, the amount of mold was the largest. The test results of aflatoxin B1 test paper and zearalenone were negative. Different oil types had significant effects on moisture, crude ash, crude fat, pH value of the feed. Different oil types had no significant effects on crude protein of the feed. Different amount of oil added had significant effects on crude protein, crude ash, crude fat, pH value of the feed. Different amount of oil added had no significant effects on moisture of the feed. The experiment indicates that feed mildew can reduce pH value of the feed. Rapeseed oil and lard do not promote the growth of aflatoxin B1 and zearalenone. [ABSTRACT FROM AUTHOR]

In this paper, the effects of emulsifier type combination, dosage, emulsification temperature and stirring speed on the stability and release performance of vegetable oil-based mold release agents were investigated using rapeseed oil as the base oil. The results showed that the optimum emulsifier combination was Span60+TW80+OP-10+SDBS; the optimum emulsifier dosage is 25% of rapeseed oil content, the optimum emulsification temperature in the oil phase was 60 °C and the optimum speed was 800 r/min, the optimum emulsion temperature is controlled at 45 °C in aqueous phase and the optimum speed was 1200 r/min. The performance test results show that the rapeseed oil-based mold release agent has a good mold release effect. The concrete adhesion is only 4.5 g/m², the drying time is 40 min, and it has no rusting effect on the mold, meeting the requirements of JC/T 949-2005 "Mold release agent for concrete products". It has been applied in the site promotion and application of the 9th standard section of Xiji high-speed project, showing good effect. [ABSTRACT FROM AUTHOR]

Silique observation and measurement are essential for rapeseed breeding. In this paper, an automatic detection method was proposed to replace the traditional manual method. A device was designed to acquire video of scattered siliques, based on pulling and vibrating stacked siliques. Silique videos were extracted to frames, and then, by using QR code as marker blocks in image, the key frames containing all siliques were effectively extracted and spliced into individual intact. Crossed siliques in frame caused an error in measurement. A cutting method of crossed siliques image based on concave point extraction and matching was proposed. By this method, all kinds of crossed siliques could be identified with accuracy rate of 98.0%. In the measurement of phenotypic parameters, a core diameter Otsu method was proposed to judge the posture of silique, by which elliptic long and short axis of the cross section of the silique was estimated, and then length, surface area and volume of the silique were calculated. Results demonstrated good accuracy and adaptability to different varieties of rape by this method. Estimation error of length, surface area and volume were less than 2.9%, 4.8% and 5.0% respectively. Thus the method could be an effective replacement of artificial way and provide key basic data for rapeseed and agricultural research fields. [ABSTRACT FROM AUTHOR]

[Objective] The present paper aimed to analyze the effects of sowing date and film mulching on yield and quality of direct seeding winter rapeseed to provide a theoretical basis for suitable sowing and high-yielding cultivation of winter rapeseed in dryland in southwest China. [Method] A two-factor completely randomized block design was adopted to explore the effect of sowing date(20th September, 30th September, 10th October, 20th October, 30th October, 10th November, 20th November) and film mulching (film mulching and no film mulching) on field soil temperature, dry matter accumulation, agronomic characteristics, yield and quality of Chuanyou 36. [Result] Film mulching effectively increased the 0-20 cm soil temperature, dry matter accumulation, plant height, length of main inflorscence and effective pods, thereby increasing rapeseed yield by 3.61%-44.47%, which was more obvious with the delay of sowing date. However, the sowing date delayed longer, dry matter accumulation and agronomic traits of rapeseed decreased significantly. The regression equation showed that the rapeseed yield rose first and then declined with the delay of sowing date, which had a significant polynomial relationship with sowing date. The optimal sowing date for rapeseed was 10th October, which was 2.13%, 47.97%, 74.19% and 136.64% higher than 30th September, 30th October, 10th November and 20th November, respectively. In addition, the delay of sowing date effectively reduced the content of linolenic acid, erucic acid and glucosinolates in rapeseed, but also reduced the oil content, while film mulching effectively decreased the difference in rapeseed quality resulted from the delay of sowing date. [Conclusion] 30th September to 10th October was a suitable sowing date for high yield of direct seeding rapeseed in dry land in southwest China, and a proper delay of the sowing period in combination with film mulching technology was more conducive to achieving goals of high yield, efficiency and quality.

[Objectives] The purpose of this paper was to clarify the effects of H2O2 immersion and sowing date on the photosynthesis, sugar metabolism and growth of rapeseed under low temperature stress.[Methods] Taking 'Nannongyou 4' as the test material and using potted plant test, the changes of H2O2(0.05%) immersion and sowing date(B1:October 5, B2:October 25, 2017) to rape biomass, photosynthesis and sugar metabolism-related indicators before and after the winter were studied.[Results] Low temperature reduced the photosynthesis capacity of rape, where in the first sowing date(B1) rape photosynthesis capacity decreased more than the second sowing date(B2). At the beginning of temperature declining, B1 rape sugar metabolism was strong, the sugar content of each sugar increased significantly, with the decrease of temperature, the sugar content decreased. B2 rape leaves sugar metabolism decreased with the decrease of temperature, and the content of sugar also decreased. H2O2 immersion reduced B1 rape photosynthesis capacity and sugar metabolism level, inhibited growth performance, and reduced biomass accumulation by 12.2% after the temperature recovery. The photosynthesis capacity of B2 rape had a catalytic effect, and by enhancing the activity of sugar metabolism-related enzymes and sugar content, sugar metabolism activities were more vigorous, growth was accelerated, and biomass accumulation increased significantly, by 44.1%.[Conclusions] H2O2 leaching treatment had different effects on the growth of rape during different sowing date before and after the winter, and the growth of B1 rape was shown as inhibition effect. For B2 rape, the growth of rape was promoted by enhancing the accumulation of biomass and by enhancing the level of photosynthesis during winter and the level of sugar metabolism. In summary, the production of H2O2 immersion technology can be applied to late-sowing rape. [ABSTRACT FROM AUTHOR]

In order to explore the effect of straw fiber on the mechanical properties of concrete, this paper researched the mechanical properties of concrete with different lengths of rape straw and fiber volume content of rapeseed under the condition that the water-cement ratio was 0.50 and the strength grade was C35. The influence of rape straw fiber on the mechanical properties of concrete was analyzed by measuring the compressive, splitting, tensile strength and flexural strength of the concrete, and the results were verified by scanning electron microscopy. The results showed that with the increase of the length and the volume content of the rape straw fiber, the compressive strength, splitting tensile strength and flexural strength first increased and then decreased. When the fiber length was 30 ~ 40 mm and the volume content was 0.1%, the compressive strength was 47.43 MPa, which was 16.45% higher than that of the control group. When the fiber length was 20 ~ 30 mm and the volume content was 0.2%, the splitting tensile and flexural strength of the concrete was 9.1 MPa and 3.71 MPa that were higher than those of the control group. Concrete internal structure with 0.2% and 0.4% fiber volume content was observed by scanning electron microscopy. It was confirmed that there was no large-area porosity at the fiber-concrete interface of 0.2% concrete, and the cement slurry on the fiber. The body was evenly distributed, and a good adsorption and adhesion force and mechanical meshing force were formed with the concrete. The internal fibers of the concrete were filled with harmful pores, no fiber agglomeration, which reduced the stress concentration and enhances the mechanical properties of the concrete.
