Conditioner for improving selenium index of citrus and using method of conditioner

Abstract

The invention belongs to the technical field of conditioners, and discloses a conditioner for improving the selenium index of citrus and a use method of the conditioner. The conditioner for improvingthe selenium index of citrus is composed of 2407.8 kg / ha of lime powder, 121.5 kg / ha of AM microbial inoculum, 93.75 kg / ha of humic acid and 562.5 kg / ha of complete-element biological organic fertilizer. Citrus trees are applied through conditioners in different proportions, relatively good treatment is found out by measuring fruit leaves and soil selenium of citrus in the whole growth period, optimization is conducted through partial regression analysis and Matlab, a scheme enabling the selenium content of the fruits to be optimal is found out, and at present, the conditioner with the optimalproportion has better influence on the selenium index compared with a contrast. The conditioner for improving the selenium index of the citrus can improve selenium in fruits and increase the contentof effective selenium in soil, so that the soil fertility is improved.

Description

technical field [0001] The invention belongs to the technical field of conditioning agents, and in particular relates to a conditioning agent for improving the selenium index of citrus and a using method thereof. Background technique [0002] At present, citrus, belonging to the Rutaceae plant, is the general name of tangerine, tangerine, orange, kumquat, pomelo, and trifoliate. It likes a warm and humid climate, and its cold resistance is slightly stronger than pomelo, lime, and sweet orange. The growth and development of citrus fruit trees, flowering and fruiting are closely related to environmental conditions such as temperature, sunshine, humidity, soil and wind, altitude, terrain and slope aspect. Citrus has a wide range of adaptation to soil, purple soil, red yellow soil, sandy beach and tidal flat, pH It can grow with a value of 4.5 to 8, and the most suitable pH value is 5.5 to 6.5. The growth of citrus roots requires a higher oxygen content, and the soil with loos...

Problems solved by technology

[0005] Through the above analysis, the problems and defects in the prior art are: in the prior art, the selection of the conditioner element types for improving the citrus selenium index is inappropriate, the ratio is unreasonable, there are many types, the pertinence is poor, the application method is unscientific, and it is difficult to improve Selenium indicator for citrus, less effective fertilizer in soil
