Fertilizer special for pakchoi

Abstract

The present invention discloses a fertilizer special for pakchoi, which comprises the following raw materials in part by weight: 20-30 parts of urea, 30-40 parts of ammonium bicarbonate, 15-20 parts of potassium chloride, 30-50 parts of biological bacteria fermentation products, 40-50 parts of rotten rapeseed cake fertilizer, 30-40 parts of oil-tea cake, 15-25parts of peanut bran, 15-20 parts of diatomaceous earth, 20-30 parts of bone meal, 2-3 parts of zinc sulfate, 1-3 parts of magnesium sulfate, 2-4 parts of sodium molybdate, 1.5-2.8 parts of borax, 15-20 parts of bentonite, 25-40 parts of humic acid, 2-5 parts of ground phosphate rock, 10-15 parts of Chinese medicine residues, 7-9 parts of garlic stems, 5-8 parts of angled bittersweet, and 5-8 parts of golden larch barks. The fertilizer is high in utilization rate. By means of the fertilizer, crops are high in yield. Meanwhile, the damage of the fertilizer to the soil ecological environment is small.

Description

technical field [0001] The invention relates to the technical field of special fertilizers, in particular to a special fertilizer for pakchoi. Background technique [0002] Fertilizers play a very important role in the growth of cabbage, and chemical fertilizers are the most common fertilizers. Generally speaking, chemical fertilizers mainly contain nitrogen, phosphorus, and potassium to supplement the lost nutrients for the soil, thereby increasing the total output of crops. However, in recent years, the utilization rate of chemical fertilizers has declined, and the output of cabbage is not as good as before. At present, scientific researchers have proposed a series of effective technical measures. At the level of fertilization, balanced fertilization technology is advocated. At the level of plant protection, biopesticides or high-efficiency, low-toxicity, and low-residue pesticides are used to replace highly toxic pesticides. In the case of high yield and high crop yield,...
