Lycium barbarum soil detection and formula fertilization method

Abstract

The invention relates to a Lycium barbarum soil detection and formula fertilization method. The method comprises the following steps: determining a collecting unit and collecting points, and then collecting soil and leaves at the marked collecting points; detecting the nutrient elements contained in soil samples and leaf samples; processing the nutrient element content detection data by using statistical analysis software to obtain the correlation between the Lycium barbarum orchard Lycium barbarum leaves in different soils and in different seed setting stages and the nutrient content of 20-60 cm soil layer soil; calculating according to the different nutrient content test values of N, P, K and trace elements in the 20-60 cm soil and the corresponding nutrient detection values of the leaves to obtain the annular fertilizer requirement, determining the distribution proportions and the corresponding application amount of N, P and K in every fertilization stage according to the annular growth and seed setting fertilizer requiring rule of the Lycium barbarum, and finally determining the application variety, the application quantity and the fertilization stage of fertilizers of N, P, K, medium elements and trace elements in different soils and Lycium barbarum orchards in different seed setting stages. The method effectively improves the output of the Lycium barbarum.

Description

technical field [0001] This application relates to a method based on soil test and fertilizer field test, according to the law of crop fertilizer demand, soil fertilizer supply performance and fertilizer effect, and on the basis of rational application of organic fertilizers, it proposes nitrogen, phosphorus, potassium and medium and trace elements, etc. The type, quantity, and method of application of fertilizers. Background technique [0002] Lycium barbarum is a multi-branched shrub plant of the genus Lycium barbarum in the family Solanaceae, and the fruit is called Lycium barbarum. The fruit is rich in nutritional elements, such as: Lycium barbarum polysaccharide, betaine, various amino acids and vitamins, rich carotenoids and trace elements, etc. It is widely used for anti-aging, anti-tumor, anti Cardiovascular and other diseases. It can be seen that wolfberry has medicinal value and economic value of traditional Chinese medicine. [0003] At present, most of the fe...

Problems solved by technology

There are following defects in this single traditional fertilization method: first, fertilization generally only pays attention to supplementing nutrients such as nitrogen, phosphorus, and potassium in the soil, while ignoring other nutrients such as magnesium, iron, zinc, etc. in the soil supplementation, so that The various nutrients in the soil are unbalanced, and the soil fertility is not good; second, when fertilizing, it is just to follow the customary and unreasonable formula, resulting in high or low soil pH value, which is not suitable for the growth of wolfberry; The method of fertilizing the soil without spraying the corresponding fertilizer on the leaves will have an adverse effect on the growth of shoot flowers and fruits of wolfberry, resulting in low yield and poor quality of wolfberry

There are also fertilization methods similar to this method, for example: the Chinese invention patent application with the application number 201510286042.0 "a method of fertilizing the early years of selenium-rich wolfberry"; the Chinese invention patent application with the application number 201410599279.X "a kind of wolfberry fertilization method”; the application number is 200610149036.1 Chinese invention patent application “Lycium barbarum special compound fertilizer, micro-fertilizer and its application method”, which all apply different amounts of N, P, and K fertilizers to Lycium barbarum plants according to different growth cycles Deep furrow fertilization and foliar spraying operations are carried out, but these methods do not carry out effective fertilization according to the growing soil environment and the age of the plants, which may lead to excessive or insufficient fertilization, which will affect the growth of wolfberry and may pollute soil
