Embodiment 1

[0012] Potassium Humate: 40

[0013] Diatomaceous earth: 40

[0014] Monoammonium phosphate: 15

[0015] Dicyandiamide: 5

[0016] The formulated soil conditioner is used for facility celery planting, with an area per mu (666.7m 2 ) Before transplanting, use 100 kg spreading; 45 days after transplanting, 100 kg per mu will be spread once again. The EC value of the soil measured at harvest is compared with the soil EC value before the soil preparation is applied. The EC value is 6.63ms / cm It was reduced to 5.17ms / cm. Compared with the control field without soil conditioner (other management measures are the same), the production of celery increased by 11.8%.

Embodiment 2

[0018] Ammonium humate: 40

[0019] Diatomaceous earth: 20

[0020] Vermiculite: 20

[0021] Monoammonium phosphate: 10

[0022] Dicyandiamide: 10

[0023] The formulated soil conditioner is used for facility cabbage planting, each acre (666.7m 2 ) 150 kg was applied to the planting pond when sowing. The EC value of the soil measured when the cabbage was harvested was compared with the soil EC value before the soil conditioner was applied. The EC value decreased by 1.58ms / cm, and the yield of cabbage increased by 1,250 kg per mu.

Embodiment 3

[0025] Potassium Humate: 20

[0026] Ammonium Humate: 20

[0027] Diatomaceous earth: 30

[0028] Monoammonium phosphate: 20

[0029] Dicyandiamide: 10

[0030] The formulated soil conditioner is used for facility sweet pepper planting, with a per mu (666.7m 2 ) 100 kg of this soil conditioner was applied to the hole when transplanting, and then 100 kg of rhizosphere per mu after 60 days. After the last harvest, the EC value of the soil sample and the EC value measured before the application of the soil conditioner are obvious Decrease from 4.76ms. / cm to 3.05ms / cm. Compared with the control without soil conditioner (other management measures are the same), the yield of sweet pepper on the plot with soil conditioner was increased by 25.1%.

Abstract

A soil conditioner for facility agriculture planting is made from the following ingredients by weight: 10-40% of humic acid salt, 20-40% of diatomite, 0-30% of vermiculite, 10-20% of ammonium phosphate, 5-10% of dicyandiamide, the humic acid salt is selected from one of potassium humate and humic acid ammonium. The diatomite, the vermiculite and the ammonium phosphate are sifted through a 40-mesh sieve respectively. The humic acid salt and the dicyandiamide are sifted through a 100-mesh sieve respectively. The raw materials are then mixed uniformly according to the proportion of ingredients. According to the invention, the soil planting environment is effectively improved, and the soil in the facility agriculture planting area is significantly improved, the ability of the soil to retain water and nutrient is enhanced, the soil EC value of the soluble salt in the soil is reduced effectively, and the resistance of crops is strengthened.

Description

technical field [0001] The invention belongs to the technical field of fertilizer production, and relates to a soil conditioner for facility agriculture planting which can improve soil water and fertilizer retention capacity and reduce soil soluble salt content. Background technique [0002] About 6 million hectares of the planting area of ​​flowers and vegetables in China belong to protected cultivation area. The following characteristics generally exist in the protected cultivation process: 1. High land utilization rate; 2. High planting density; 3. Serious occurrence of diseases and insect pests; 4. The use of pesticides and chemical fertilizers is large; five, the rapid deterioration of the farming environment and other phenomena. The secondary salinization of soil caused by protected cultivation in such a high temperature, high humidity, closed or semi-closed environment has a very prominent impact on high-quality, stable and high-yield crops.
