[Objective] This paper aimed to the problem that application of chemical fertilizers and pesticides and long-term continuous culti vation mode in the industry caused the yield and quality of Lycium barbarum L had declined in recent years, and the effects of different mi crobial agents on the growth and development of the L. barbarum L. and fruit yield and quality were studied. [Method] Ningqi No. 7 L. barba rum L. was used as experimental material, and the field trials with no microbial agents as a control were conducted by the application of Tl, T2, T3 three microbial agents. [ Result] Each treatment had different degrees of promoting effects on the vegetative growth, reproductive growth, yield and quality of L. barbarum L. plants. Microbial agents could significantly increase the survival rate of first-year L. barbarum L. seedlings, and the amount of roots and branch growth by 9. 06% - 57. 84% and 4. 76% - 54. 9%, respectively; Microbial agents could in crease the number of branches, branch growth and SPAD value of fourth-instar L. barbarum L. plants by 29. 9% - 87. 09%, 7. 5% - 18. 3%, and flower formation rate, fruit setting rate, 100-seed weight and yield by 2. 07% - 18. 87%, 3.19% - 13. 63%, 0.57% - 4. 92%, 29. 7% - 52. 7%, respectively; Especially, T2 had the most significant effect, compared with other treatments, the amount of branches, flower formation rate and yield were increased by 30. 05%, 12. 23% and 4. 45%. Microbial agents could significantly improve fruit quality and increase the content of polysaccharides, betaine, total flavonoids, and carotene in L. barbarum L. fruit by 4. 55% 25%, 25. 5% - 43. 67%, 12. 5% - 58%, and 2. 8 - 3. 6 times, respectively. Especially, Tl had the most significant effect on the improvement of quality indicators, compared with other treatments, the content of polysaccharides, betaine and carotene increased significantly by 5. 77%, 8. 52% and 23. 78%. [ Conclusion] Comprehensive evaluation of the analysis results showed that the three combinations of microbial agents tested had a certain positive effect on growth of L. barbarum L. . T2 had the most significant effect on tree growth, yield and economic benefits, Tl had the best effect on fruit quality, and it could be used for reference and promotion according to production needs in production practice, Tl and T2 could be used together to achieve the effect of improving quality and increasing production.

【Objective】It is aimed to explore the effects of applying bag-controlled release fertilizer for many years on the growth,yield and quality of peach.【Method】Taking ’wanhujing’ and ’xiacui’ as materials, we explored the effects of applying bag-controlled release fertilizer for 3 years on the growth of branches,leaves and fruits,yield,quality and economic benefit of peach.【Result】The length of primary tillers, number of secondary tillers,Titrable Acidity,output value data per unit area of ’wanhujing’or’xiacui’were remarkably or extremely remarkably lower than CK1 or CK2 when applying bag-controlled release fertilizer;While the diameter of primary tillers and secondary tillers,chlorophyll a content,chlorophyll b content,total chlorophyll content,weight of single fruit,fruit longitudinal diameter,soluble solid content,contents of total sugar,solidity-acid ratio were remarkably or extremely remarkably higher than CK1 or CK2.【Conclusion】Applying bag-controlled release fertilizer for several consecutive years can effectively increase regeneration length and diameter of renewal branches,extend canopy, improve plant light conditions, enhance the peach plant growth, improve the quality of the fruit flavor, which is a convenient and efficient fertilization schedule for peach orchard.

【Objective】 This study aimed to further clarify the mechanism of reasonable dense planting and yield increase of spring maize in dryland of the Loess Plateau in southern Ningxia and provide theoretical and technical support for high-yielding cultivation of maize in arid and semi-arid regions. 【Method】 In this experiment, a randomized block design method was used, two large-scale maize varieties, Dafeng 30 and Xianyu 698 were used as the test materials, and five density gradients were set to study the planting density of the major agronomic traits of the maize cultivars, including traits, dry matter accumulation, yield and yield-related traits, etc. 【Result】 With the increase of the density, plant height and ear height of different maize varieties gradually increased. Dry matter accumulation gradually increased with the advancement of the growing period, and the dry matter accumulation of the two varieties reached a maximum at the ripening stage. The leaf area index of the population increases gradually with the increase of the density. The relative chlorophyll content gradually decreased with the increase of the density. With the increase of the density, the ear weight, ear diameter, grain number per row, grain weight per ear, grain weight per hectare, yield of the two varieties increased first and then decreased, and the baldness rate decreased first and then increased. Both varieties were at the output of 67 500 plants/hm2, the highest yield was achieved, which was an increase of 73.39 % and 36.26 % over the 52 500 plants/hm2. 【Conclusion】 Under the conditions of this experiment, the suitable density of Dafeng 30 and Xianyu 698 was 67 500 plants/hm2.
