Embodiment 1

[0018] 20kg of polyacrylamide, 30kg of polyaspartic acid and 10kg of boric acid were dissolved in 940kg of water to obtain a mixed solution; 830kg of powdered coco peat, 80kg of diatomaceous earth and 30kg of humic acid were mixed uniformly to obtain a solid powder mixture; then Spray the mixed solution into the solid powder mixture, mix and stir evenly; ventilate and dry at room temperature to obtain the finished soil conditioner.

[0019] The soil improver that makes is applied to the slightly alkaline soil (salt concentration 0.86g / kg, pH8.07, bulk density 1.39g / cm2) of Jiading District, Shanghai 3 ), the amount of 500kg soil conditioner applied per mu is evenly mixed with the soil. The improved soil was compared with the unimproved soil, and watered twice a day. One week later, the above soil was sampled and analyzed, and the results showed that the improved soil had a salt concentration of 0.51g / kg, a pH of 6.71, and a bulk density of 1.08g / cm 3 , while the unimproved s...

Embodiment 2

[0021] 15kg of polyacrylamide, 40kg of polyaspartic acid and 15kg of boric acid were dissolved in 930kg of water to obtain a mixed solution; 800kg of powdered coco peat, 90kg of diatomaceous earth and 40kg of humic acid were mixed uniformly to obtain a solid powder mixture; then Spray the mixed solution into the solid powder mixture, mix and stir evenly; ventilate and dry at room temperature to obtain the finished soil conditioner.

[0022] The soil improver that makes is applied to the slightly alkaline soil (salt concentration 0.86g / kg, pH8.07, bulk density 1.39g / cm2) of Jiading District, Shanghai 3 ), the amount of 500kg soil conditioner applied per mu is evenly mixed with the soil. The improved soil was compared with the unimproved soil, and watered twice a day. One week later, the above soil was sampled and analyzed, and the results showed that the improved soil had a salt concentration of 0.58g / kg, a pH of 6.59, and a bulk density of 1.16g / cm 3 , while the unimproved s...

Embodiment 3

[0024] 10kg of polyacrylamide, 30kg of polyaspartic acid and 10kg of boric acid were dissolved in 950kg of water to obtain a mixed solution; 860kg of powdered coconut peat, 60kg of diatomaceous earth and 30kg of humic acid were mixed uniformly to obtain a solid powder mixture; then Spray the mixed solution into the solid powder mixture, mix and stir evenly; ventilate and dry at room temperature to obtain the finished soil conditioner.

[0025] The soil improver that makes is applied to the slightly alkaline soil (salt concentration 0.86g / kg, pH8.07, bulk density 1.39g / cm2) of Jiading District, Shanghai 3 ), the amount of 500kg soil conditioner applied per mu is evenly mixed with the soil. Tomatoes were grown and compared to soil without the use of soil amendments. The results showed that for one season of tomatoes, the yield of the improved soil was 5860kg / mu, which was 37.9% higher than the yield of the unimproved soil (4250kg / mu).

Abstract

The invention relates to a soil improver containing coconut chaff and a preparation method thereof, and relates to a soil improver. The soil improver containing the coconut chaff comprises the following components by weight percent: 0.75 to 0.92 percent of coconut chaff, 0.05 to 0.1 percent of diatomite, 0.01 to 0.05 percent of polyaspartic acid, 0.01 to 0.05 percent of humic acid, 0.005 to 0.03 percent of polyacrylamide and 0.005 to 0.02 percent of boric acid. The preparation method comprises the following steps: (1) dissolving polyacrylamide, polyaspartic acid and boric acid in water to obtain a mixed solution; (2) uniformly mixing powdered coconut chaff, diatomite and humic acid to obtain a solid powdered mixture; (3) spraying the mixed solution obtained in the step (1) into the solid powdered mixture obtained in the step (2), mixing, and air-drying to obtain the soil improver containing the coconut chaff. The production cost is low, raw materials are environmentally friendly and non-toxic, the secondary salinization and hardened soil can be effectively improved, and the productivity of the earth can be restored and improved.

Description

technical field [0001] The invention relates to a soil improver, in particular to a soil improver containing coconut bran and a preparation method thereof. Background technique [0002] Secondary salinization is the process of soil salinization caused by unreasonable cultivation, irrigation and excessive fertilization. The content of organic matter in soil is an important indicator of soil fertility and aggregate structure, and the reduction of organic matter leads to soil compaction. my country's agricultural arable land area is limited, and in recent years, with the application of a large amount of inorganic fertilizers, irrational irrigation and the acceleration of urbanization, non-agricultural development and occupation of arable land and other artificial and unreasonable factors have led to sand petrification of arable land around urban areas, Problems such as secondary salinization and soil compaction are intensifying day by day, with characteristics such as high pH v...
