Abstract

The invention relates to a bunching onion growth slow-release BB fertilizer, and belongs to the technical field of bunching onion fertilizer production. The bunching onion growth slow-release BB fertilizer is prepared from coated urea, a potash fertilizer, an organic fertilizer and a secondary element fertilizer specially required by bunching onion growth; the slow-release BB fertilizer is prepared from 43%-50% of the coated urea, 35%-40% of the potash fertilizer, 10%-15% of the organic fertilizer and 4%-6% of the secondary element fertilizer, wherein the coated urea comprises urea, zeolite and a compound fertilizer binder; the slow-release BB fertilizer can be prepared by mixing in a proper proportion according to growth requirements of the bunching onion, can be used as a base fertilizerto be applied once, does not need topdressing later, saves labor and time, is high in utilization rate of coated urea, can reduce loss of the urea and ammonia generated by decomposition of the urea,can be quickly absorbed by roots of the red onions, and is simple in preparation method and convenient to operate.

Description

technical field [0001] The invention relates to a slow-release BB fertilizer for shallot growth, belonging to the technical field of shallot fertilizer production. Background technique [0002] Red onion is a cultivar of Fen onion. It has a mellow aroma and good quality. It is favored by consumers. Shuili Zhongxin Village, Jianggao Town, Baiyun District, Guangzhou City has the reputation of "the hometown of red onions". The red onion production base has a smooth market, good economic benefits and obvious industrial advantages. The use of conventionally sold fertilizers on the market not only does not solve the problem of soil acidification and increases the yield of shallots, but also uses a large amount of chemical fertilizers, and the higher price increases the burden on farmers. At the same time, urea is easy to volatilize, and it is easy to lose, and most of the nutrients are lost. It needs multiple fertilization to supplement the nutrients needed for the rapid growth o...
