Description
Technical Field
The invention relates to the technical field of fertilizers, in particular to a large-particle fertilizer applied to sweet potatoes.
Background
The fertilizer frequently used in sweet potato production comprises nutrients such as nitrogen, phosphorus, potassium and trace elements, and most of the traditional fertilizers are powdery or granular with the particle size within 5 mm. The traditional fertilizer has the following four defects: firstly, the traditional fertilizer has small particles and high water melting speed, so that a large amount of fertilizer is lost and volatilized along with rainwater, and is really absorbed by crops by less than 40 percent; secondly, the traditional fertilizer has fast loss and short detention time in soil, so that the crops in one season must be divided into a plurality of times to be fertilized, which takes labor; thirdly, because the traditional fertilizer has small particles, farmers are difficult to accurately master the fertilizing amount each time in mountainous areas or areas where manual fertilization is performed, the fertilizing amount is easy to be insufficient or excessive, the yield of crops is reduced and the fertilizer is wasted by light people, and the roots and the seedlings are burned and the crops are no longer harvested by heavy people. Fourthly, the method comprises the following steps: although many controlled release fertilizers are available on the market, most of them are made by spraying sulfur, resin and other waterproof organic matters on the surface of large-particle urea, such as: the core fertilizers selected by Chinese patent publications CN101177365A, CN101200399, CN101362664A and the like have small particles, the diameter is generally 3-5 mm, the surface area of the fertilizer per ton is large, the coating materials are much used, and the coating materials are generally used by 20 percent, so the cost is increased, and the original content of the fertilizer is reduced. For example, the Canadian Chinese maple controlled release urea has the nitrogen content after coating of about 37 percent, and the factory price is about 1000 yuan/ton higher than that of the common urea and 1 time higher than that of other nitrogen fertilizers with the same content. The increased benefit is far less than the increased cost, and therefore, the promotion in the market is difficult all the time.
