Problems solved by technology

For the production and cultivation of Nanguo pear, the effective period of ordinary fertilizer is short, and the release of nutrients in the fertilizer, especially nitrogen, cannot meet the demand for nitrogen fertilizer for the growth of Nanguo pear trees. The release of nutrients is inconsistent with the demand for nutrients of Nanguo pear trees. The concentrated release of nutrients or the uncoordinated release ratio of nutrients lead to low fertilizer use efficiency and nutrient stress on the growth of Nanguo pear trees. A large amount of nutrients are released when a large amount of nutrients are not needed, and there is not enough nutrients when a large amount of nutrients are needed. Therefore, it will cause nutrient stress to the growth of Nanguo pear trees, which will seriously affect the quality of Nanguo pears and cause ecological environment pollution in orchards.

Embodiment 1

[0019] The fertilizer consists of urea-based nitrogen fertilizer, phosphate fertilizer, potassium fertilizer, medium elements and trace elements. The urea-based nitrogen fertilizer is calculated by the amount of urea pure nitrogen: ordinary urea (large granule urea) accounting for 12.5% ​​of urea pure nitrogen (Shanxi Lanhua brand large granule Urea), polypeptide urea (aspartic acid urea) accounting for 12.5% ​​of urea pure nitrogen, 30-60 days slow-release urea accounting for 12.5% ​​of urea pure nitrogen, 50-80 days of 18.75% of urea pure nitrogen adding DCD and NBPT resin-coated urea (it is prepared as described in CN101200399 according to the publication number), 80-90 days sulfur-coated urea (purchased from Shanghai Hanfeng) accounting for 12.5% ​​of urea pure nitrogen and accounting for urea pure nitrogen 18.75% 120-180 days resin-coated urea (purchased from Kingenta);

Abstract

The invention relates to nanguo pear cultivation, in particular to a dedicated fertilizer for producing green nanguo pear and a preparation and an application method thereof.The fertilizer is composed of urine-based nitrogenous fertilizer, phosphate fertilizer, potash fertilizer, medium elements and trace elements; in the preparation method, the urea-based nitrogenous fertilizer, phosphate fertilizer and potash fertilizer with a grain size of 1.5-4.5mm serve as solid raw materials; then the medium elements are added to humic acid or humic acid salt accounting for 60-100% of the mass percent of the medium elements to be mixed; afterwards, trace elements are added and mixed with the mixture, cementing agent is used for pelleting and producing solid raw materials with a grain size of 1.5-4.5mm for standby use; finally, the medium elements and trace elements mixed for pelleting are uniformly mixed with the urine-based nitrogenous fertilizer, phosphate fertilizer and potash fertilizer.The dedicated fertilizer is applied to the nanguo pear trees as spring base fertilizer at one time and no after manuring is not needed.The nitrogenous fertilizer use level in the fertilizer of the invention and different number of nanguo pear fruit indexes with proportion fully following nanguo pear of different tree ages form five-level supply speed of fertilizer nitrogen, thus remarkably controllingloss of nitrogenous fertilizer.

Description

technical field [0001] The invention relates to the cultivation of Nanguo pear, in particular to a special fertilizer for the production of green Nanguo pear fruit and its preparation and application method. Background technique [0002] Nanguo pear is one of the unique pear varieties in China. Nanguo pear belongs to the Qiuzi pear system. It is native to Anshan, Liaoning, and is a natural hybrid offspring. This variety is famous for its bright fruit color, soft flesh, sweet and sour taste, juicy flavor, and strong aroma. It is well-known at home and abroad, and is increasingly favored by the international market. Nanguo pear is a local characteristic variety in Liaoning Province. It has been cultivated on a large scale in various pear producing areas in Liaoning Province. Jilin and Heilongjiang also have a certain scale of cultivation, and it shows a sustainable development momentum. At present, ordinary fertilizers are mainly used in the cultivation process of Nanguo pear...
