Bag-controlled sustained release fertilizer for mango tree and application method thereof

Abstract

The invention discloses a bag-controlled sustained release fertilizer for a mango tree and an application method thereof. The bag-controlled sustained release fertilizer for the mango tree specifically involves preparation of a fertilizer bag, compositions of a fertilizer, and a fertilizer application method. According to the bag-controlled sustained release fertilizer for the mango tree and the application method thereof, a package bag is made of paper; the package bag is started to decompose spontaneously two years after the fertilizer is applied; soil and air are not polluted, and a soil loosening effect is achieved. Meanwhile, the fertilizer efficiency of the bag-controlled sustained release fertilizer is long; the nutrient utilization rate is high. The effects of improving crop yieldand improving crop quality can be achieved. The manpower and material resources used for applying the fertilizer can also be saved effectively; the fertilizer is really applied quantitatively and accurately according to the requirement of the mango tree; meanwhile, the concentration of quick effective nutrients of the soil can be kept stable; the defect that the nutrient concentration of fertilizer applied soil fluctuates greatly is overcome; the nitrogen utilization rate is improved by 10 percent. In addition, the effects of protecting oil and reducing environment pollution are also achieved.By promoting and applying the bag-controlled sustained release fertilizer, safety and environment friendliness can be achieved; the bag-controlled sustained release fertilizer has long-term ecological benefits and remarkable social and ecological benefits, benefits the nation and the people, and has a very broad prospect.

Description

technical field [0001] The invention relates to a new technology field of fruit tree cultivation, production and management, in particular to a bag-controlled slow release of fertilizer for mango fruit trees and an application method. technical background [0002] With the higher pursuit of human beings to the environment, health and harmonious goals, some doubts and worries are also blurring people's recognition of fertilizers. Traditional fertilizers include various compound fertilizers, compound fertilizers, single-element and multi-element fertilizers, etc. These quick-acting fertilizers, which are applied loosely, have a quick effect after use, but the fertilizer effect is short, and the crop absorption capacity is limited. It is difficult for the nutrients to be completely absorbed in a short time after fertilization. and other reasons, resulting in huge waste, the nutrient utilization rate is generally about 15-30%, and the utilization rate is lower in sandy soil.

These quick-acting fertilizers, which are applied loosely, have a quick effect after use, but the fertilizer effect is short, and the crop absorption capacity is limited. It is difficult for the nutrients to be completely absorbed in a short time after fertilization. and other reasons, resulting in huge waste, the nutrient utilization rate is generally about 15-30%, and the utilization rate is lower in sandy soil

Not only endangering the environment, but also endangering food safety

[0003] In addition, the current phenomenon of "tasteless vegetables, unscented fruits, and unsweet melons" is directly related to excessive and unreasonable use of chemical fertilizers
