Problems solved by technology

[0004] The basic fertilizers for crops are usually nitrogen, phosphorus, and potassium. Nitrogen fertilizers are beneficial to the growth of leaves of crops, phosphorus fertilizers are beneficial to the growth of flowers and fruits of crops, and potassium fertilizers are beneficial to the growth of branches and stems of crops. Now they are used for foliar spraying All selenium fertilizers use sodium selenite without exception. In

Embodiment Construction

[0009] According to different crops, and the variety and quantity of pesticides they use, choose "potassium selenite" selenium fertilizer with a pH ranging from 7.2-8.5 and a concentration of 100-500ppm, and spray it on the leaves of the plants according to certain specifications. The amount of application varies with different types of crops. Selenium fertilizer is sprayed on the leaves of plants and is quickly absorbed by plants. Different crops are harvested after different days to achieve the effect of increasing production and income and degrading residual pesticides to zero.

[0010] Implemented example:

[0011] 1. Spray the "potassium selenite" with a concentration of 200ppm at pH 7.1 on the rice. When harvested, the selenium content in the rice rises from 0.07PPm to 0.22PPm-0.29PPm, and the selenium content in the bran increases from 0.011 PPm rises to 0.21PPm.

[0012] 2. Use "potassium selenite" with a concentration of 500ppm at pH 7.3 to spray on the tea leaves. W...

Abstract

The invention discloses a potassium-containing selenium fertilizer for promoting plant growth and deteriorating pesticide residue. The potassium-containing selenium fertilizer adopts the technical scheme that selenious acid is generated firstly and then neutralized by potassium hydroxide so as to obtain potassium selenite. According to the deterioration requirement of different crops and different pesticides, the potassium selenite is prepared into the selenium fertilizer of 'potassium selenite kind' with the pH value of 7.2 to 8.5, and the concentration of 100 ppm to 500 ppm. The potassium-containing selenium fertilizer substitutes sodium selenite (sodium is a redundant element in the fertilizer) to serve as the selenium fertilizer which is sprayed on the leaves of the plant, so that the dual manurial effect of the selenium fertilizer and a common potash fertilizer can be achieved. After the leaves of the plant are sprayed with the fertilizer, the plant can be harvested at different time intervals, so that the effects of increasing the yield and deteriorating pesticide residue can be achieved.

Description

technical field [0001] The invention belongs to special fertilizers in agricultural fertilizers. Background technique [0002] At present, there are many agricultural fertilizers and pesticides. Fertilizers are mainly nitrogen fertilizers, phosphorus fertilizers, potassium fertilizers, compound fertilizers, biological fertilizers, organic fertilizers, trace element fertilizers, etc. Selenium fertilizer is a new variety, which has the effect of significantly increasing crop production. The application of selenium has been done in recent decades. Due to the familiarity with the application of sodium selenite, sodium selenite is used in animals at home and abroad without exception. When selenium fertilizer is applied to plants, there is one kind of In addition to mixed slag as base fertilizer, sodium selenite is also used as selenium fertilizer for foliar spraying without exception. Because it contains selenium, selenium is an element with special physiological activity. Its op...
