The correct use of micro-fertilizer is one of the key measures to promote high-quality and high-yield vegetables. However, the unscientific application of many farmers in the application of micro-fertilizer not only causes serious waste, increases production costs, but also poisons vegetables and destroys the soil environment. Not conducive to the growth of vegetables. The safe use standards for commonly used micro-fertilizers for vegetables are:
The application rate of ferrous sulfate is not more than 3.25 kg per mu, and the spraying concentration of the foliage of the plant is preferably 0.1%-0.2%. After the application of ferrous sulfate, it is necessary to apply some high-quality farmyard manure to improve the soil to promote the absorption and action of ferritin.
Manganese sulfate and manganese chloride The soil application is not more than 2.05 kg per mu, the soaking concentration is 0.05-0.1%, and the foliar spray concentration is 0.05-0.15%.
Copper sulphate The application rate of soil is not more than 2 kg per mu, the soaking concentration is 0.01-0.05%, and the foliar spray concentration is 0.02-0.04%. Generally, it can be combined with anti-disease sprayed Bordeaux mixture, one of the main components is copper sulfate. After spraying, both cure and increase fat.
The application amount of borax and boric acid is not more than 1.25 kg per mu, the soaking concentration is 0.02%-0. 05%, and the foliar spray concentration is 0.3-0.5%.
