A kind of rubber tree high-concentration formula fertilizer and preparation method thereof

Abstract

The invention provides a rubber tree high-concentration formula fertilizer and a preparation method thereof. The raw materials of the formula fertilizer include 90-95% inorganic fertilizer and 5-10% compound gain fertilizer according to weight percentage; N, P in the inorganic fertilizer 2 o 5 and K 2 The mass percentage of O is 20-23%: 10-12%: 13-15%, N+P in inorganic fertilizer 2 o 5 +K 2 The mass percent content of O total nutrient is 43~50%; Described composite gain fertilizer, according to the ratio of mass and number, comprises: 1~3 parts of calcium nitrohumate fertilizer, 1~2 part of silicon humate fertilizer, 1 part ~2 parts of nitrohumic acid magnesium fertilizer, 10~15 parts of attapulgite and 6~12 parts of red sandstone; the high-concentration formula fertilizer for rubber trees prepared by the present invention can effectively improve the absorption and utilization rate of fertilizers and increase the output per unit area of ​​rubber trees , and improve the soil structure and promote soil nutrient balance, fully accelerate the growth and thickening of small and medium seedlings, and increase the growth rate of rubber trees.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a rubber tree high-concentration formula fertilizer and a preparation method thereof. Background technique [0002] The land resources suitable for planting rubber trees in our country are limited, and the potential of the natural rubber industry to increase production capacity by expanding the planting area and expanding the scale is getting smaller and smaller. The continuous in-depth research on the development and application technology of rubber tree formula fertilizers has great impact on improving the yield per unit area of ​​cut trees and It is of great significance to realize the rapid growth of small and medium-sized seedlings. [0003] In the planting and production of rubber, due to the limited absorption and utilization rate of fertilizers by rubber trees, the current rubber formula fertilizers are mostly limited to low-concentration fertilizers, and...

AI Technical Summary

Problems solved by technology

[0003] In the planting and production of rubber, due to the limited absorption and utilization of fertilizers by rubber trees, the current rubber formula fertilizers are mostly limited to low-concentration fertilizers, and the total nutrient content is usually below 30%. However, under the fertilization conditions of low-concentration fertilizers, There are deficiencies such as poor fertilization effect, slow growth of medium and small seedlings, and low yield per unit area of ​​rubber trees; in addition, rubber plantations are mostly planted in hilly areas, and low-concentration fertilizer application techniques often easily lead to increased transportation costs and fertilization labor costs. question

In the study of the effect of high-concentration fertilizers, high-concentration compound fertilizers for economic crops such as rice and vegetables are involved. For example, Wang Kaijun compared the performance of five high-concentration compound fertilizers on rice; Huang Qing et al. Experiments on the effects of high-concentration water-soluble fertilizer Prodan on tomato yield, quality and soil have been carried out, but there are no relevant reports on the trial production of high-concentration fertilizers and their application effects
