Abstract

The invention provides a potato water-soluble fertilizer and an applying method thereof. The potato water-soluble fertilizer consists of the following components: 100-500 parts by weight of urea, 100-500 parts by weight of monopotassium phosphate, 100-600 parts by weight of potassium nitrate, 10-500 parts by weight of potassium sulphate, 1-10 parts by weight of polymerized boron, 1-5 parts by weight of molybdate, 1-10 parts by weight of chelated zinc, 1-10 parts by weight of chelated copper, 1-40 parts by weight of chelated calcium, 1-20 parts by weight of chelated magnesium, 1-10 parts by weight of chelated manganese, 1-10 parts by weight of potassium metasilicate, 1-10 parts by weight of potassium alginate, 1-5 parts by weight of chitosan oligosaccharide, and 1-3 parts by weight of silicon dioxide anticaking agent. The potato water-soluble fertilizer can greatly increase the chlorophyll content, the photosynthetic net assimilation rate and the root system activity of potato, increase the tuber number of each single plant, increase the weight of each tuber, increase the commodity potato rate, and increase the contents of starch, protein, and vitamin C.

Description

technical field [0001] The invention belongs to the field of functional water-soluble fertilizers, and in particular relates to a water-soluble fertilizer capable of improving potato yield and quality and an application method. Background technique [0002] my country is a large potato producing country, and the planting area is increasing year by year. Potatoes have high yield, rich nutrition, short growth period, simple management, and wide processing uses. important role. Potatoes have high nutritional value and are deeply loved by people. Potato protein is better than soybean, the closest to animal protein, and rich in lysine and tryptophan, which is incomparable to ordinary grains, and rich in potassium , zinc, iron food. The protein and vitamin C it contains are 10 times that of apples, and the content of vitamins B1, B2, iron and phosphorus is much higher than that of apples. From a nutritional point of view, its nutritional value is equivalent to 3.5 times that of ...
