Special fertilizer used in flowering and pod setting stage of soybeans

Abstract

The invention discloses a special fertilizer used in the flowering and pod setting stage of soybeans. The special fertilizer is prepared from urea, licorzinc, magnesium ascorbyl phosphate, baking powder, sodium bicarbonate, attapulgite, potassium fulvate, ascorbic acid, potassium dihydrogen phosphate, plant extract, borax, calcium superphosphate, starch and water. The special fertilizer used in the flowering and pod setting stage of soybeans can improve a photosynthesis utilization rate and soybean growth; and the added plant extract, magnesium ascorbyl phosphate and licorzinc can inhibit bacteria, kill insects and prevent diseases, have no toxic and side effect on crops and human body, improve the flowering rate and fruiting rate of soybeans and promote development of soybean fruit. All the components of the special fertilizer cooperate with each other and produce synergistic effect, so the special fertilizer can supply soybeans with nutrient elements needed by growth and development of the soybeans in the flowering and pod setting stage and has the advantages of complete nutrients, multiple functions, high comprehensive fertility, great yield increase potential and capacity of improving soybean output and soybean quality.

Description

technical field [0001] The invention relates to the field of chemical fertilizers, in particular to a special fertilizer for soybean flowering and pod setting. Background technique [0002] Fabaceae soybean is an annual herb, called Shu in ancient China, is a legume plant whose seeds are rich in protein, soybean is oval, spherical, yellow, light green, black, etc., so there are soybeans, green beans, black beans known as. It needs sufficient sunlight and requires more nitrogen, phosphorus, and potassium nutrients. Farmers generally do not have scientific planting methods, and are blind and random; especially fertilization, most farmers planting soybeans use traditional methods to fertilize blindly, which not only wastes a lot of resources and pollutes the environment, but the flowering period of soybeans is from the beginning of flowering to the end of flowering. . Soybean enters the flowering stage, which is a stage of vegetative growth and reproductive growth, but veget...

Problems solved by technology

The growth of pods first increases in length, then increases in width, and finally increases in thickness. This period is a very critical period for soybean development, while traditional soybean planting does not pay much special attention to this period, or just a large amount of nitrogen and phosphorus topdressing Potassium fertilizers, the effect is not obvious, and it will cause waste of chemical fertilizers and increase costs
