Problems solved by technology

[0007] (3) Although the application of phosphorus activators can activate phosphorus in the soil, some of them can kill beneficial microorganisms in the soil
[0008] (4) Some phosphorus activators are likely to cause soil pollution due to their residual properties. After being absorbed by crops, they can affect the quality of agricultural products and even be harmful to humans and animals.
[0012] Since the 1870s in my country, more phosphorus fertilizers have been applied to the soil. Since the utilization rate of phosphorus is generally not more than 25%, a large amount of phosphorus resources have been accumulated in the soil, and most of these phosphorus are fixed in the ineffective state. The soil cannot be absorbed and utilized by crops; in addition, the effectiveness of the phosphorus fertilizer applied in agricultural production is reduced due to the rapid fixation and sedimentation of the soil, which leads to a high input of phosphorus fertilizer and increases the cost of agricultural production

Embodiment 1

[0035] 50kgH 2 , 40kgHA, and 10kg zeolite powder were crushed and mixed in proportion to form a homogeneous body, which is the soil phosphorus activator. Get above-mentioned material (activator) 5kg and diammonium phosphate 6kg, urea 11kg, KCl 6kg is used for 1 mu of land, planting corn, yield increases than control group (mu applies phosphorus amount (diammonium) 9kg, urea 8kg, KCl 6kg) 6.3%.

Embodiment 2

[0037] 40kgH 2 , 40kgHA, and 20kg bentonite were crushed and mixed in proportion to form a homogeneous body and form a soil phosphorus activator. Soil phosphorus activator 6g / pot, N 3.8g / pot, P 2 o 5 2g / pot, KCl 1g / pot, every pot is filled with 12.5kg air-dried black soil (crossing a 5mm sieve), planting soybeans, in the time of 20 days after planting, the available phosphorus ratio in the soil was higher than that of the control group (applying P 2 o 5 3g / pot, N 3.8g / pot, KCl 1g / pot) increased by 20.3%, increased by 36.1% on the 50th day, plant height increased by 2.7cm increased by 3.1%, hundred-grain weight increased by 0.6g, and reduced phosphorus input by 1 / 3 In the case of 11.7% increase in production.

Abstract

The invention discloses a soil phosphor activator and using method, which comprises the following parts: 30-50% complex builder H2, 30-40% humic acid HA and 10-40% filler, wherein the complex builder H2 is alkaline paper making waste-liquid drier.

Description

technical field [0001] The invention relates to a technique for improving the availability of soil phosphorus, in particular to a soil phosphorus activator and an application method. Background technique [0002] The shortage of phosphate fertilizer resources and the low content of available phosphorus in soil have become the limiting factors for the sustainable development of agriculture in my country. Due to the influence of the characteristics of phosphorus fertilizer and the limitation of cultivation techniques, only 15-20% of the phosphorus applied in the soil is absorbed and utilized by the crops of the current season, and the aftereffect of the crops is generally no more than 25% (Wang Qingren et al., 1998 ). Especially in the use of long-acting compound fertilizers, due to the uncoordinated release of N and P, it is more difficult to exert the fertilizer effect of phosphate fertilizers. In agricultural production, improving the utilization rate of phosphate fertiliz...
