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

The soil conditioner of industrialized agriculture plantation usefulness

Technical field

The invention belongs to the fertilizer production technology field, is a kind of soil water-reataining fertilizer-keeping of raising ability that has, and reduces the soil conditioner of the industrialized agriculture plantation usefulness of soil soluble salt content.

Background technology

In the cultivated area of Chinese flower, vegetables, have 6,000,000 hectares approximately and belong to the facility cultivation area, the following characteristics of ubiquity in the facility cultivation process: one, land utilization ratio is high; Two, planting density is big; Three, disease and pest takes place serious; Four, agricultural chemicals, chemical fertilizer usage quantity are big; Five, the rapid phenomenon such as deterioration of farming environment.The soil secondary salinization phenomenon that in this high temperature of facility cultivation, high humidity, sealing or semi-enclosed environment, causes is very outstanding to the influence that crop high quality and stable yield high yield causes.

Summary of the invention

Outstanding problem to above-mentioned existence; The present invention provides a kind of soil conditioner of industrialized agriculture plantation usefulness; We are through experimental study for many years; This of screening is the soil conditioner of host with humate and natural mineral sorbent material, with the utilization ratio that improves nitrogenous fertilizer obvious effect arranged all for reducing soil soluble salt total amount.It is that a kind of technology is simple, cost is low, and raw material is sufficient, the tangible soil conditioner of effect, and being used to overcome the continuous cropping obstacle of industrialized agriculture plantation and reducing planting cost all has significant effect.

The soil conditioner of this industrialized agriculture plantation usefulness that the present invention proposes is mixed and made into by following raw materials by weight calculating:

Humate 10-40, zeyssatite 20-40, vermiculite 0-30, monoammonium phosphate 10-20, Dyhard RU 100 5-10,

Described humate is selected potassium humate or ammonium humate for use.

The preparation method of said soil conditioner is: zeyssatite, vermiculite and monoammonium phosphate pulverize separately are crossed 40 mesh sieves, and humate and Dyhard RU 100 pulverize separately are crossed 100 mesh sieves, press formula rate then material mixing is evenly got final product.

This amendment that the present invention proposes can effectively improve the soil planting environment; For the soil of planting in the industrialized agriculture zone tangible improving effect is arranged; Improve the preserve moisture and fertility ability of soil, effectively reduced soil EC value in the content of soluble salt in the soil, improved the resistance of crop.

Embodiment:

The present invention all can reach tangible soil opsonization by the given weight percent preparation of following embodiment.

Embodiment 1

Potassium humate: 40

Zeyssatite: 40

Monoammonium phosphate: 15

Dyhard RU 100: 5

The soil conditioner of preparation is used for the plantation of facility celery, every mu of (666.7m ²) spread fertilizer over the fields with double centner before transplanting; Transplanting back 45 days every mu of double centners spreads fertilizer over the fields once again; Survey the soil EC value soil EC value preceding during results relatively with not executing the soil blender; The EC value is reduced to 5.17ms/cm by 6.63ms/cm, celery with without (other control measures are identical) of soil conditioner contrast field piece relatively, raising the output 11.8%.

Embodiment 2

Ammonium humate: 40

Zeyssatite: 20

Vermiculite: 20

Monoammonium phosphate: 10

Dyhard RU 100: 10

The soil conditioner of preparation is used for the plantation of facility Chinese cabbage, every mu of (666.7m ²) when sowing the kind pool spread manuer in holes 150 kilograms, survey soil EC value during the Chinese cabbage results and compare, the EC value 1.58ms/cm that descended, then 1250 kilograms of the every mu of increases of Chinese cabbage output with the soil EC value of not executing before the soil conditioner.

Embodiment 3

Potassium humate: 20

Ammonium humate: 20

Zeyssatite: 30

Dyhard RU 100: 10

The soil conditioner of preparation is used for the plantation of facility pimento, every mu of (666.7m ²) this soil of double centner amendment of spreading manuer in holes when transplanting; After 60 days more every mu of double centner rhizosphere use once; Behind the last harvest home; Soil sampling is surveyed the EC value has obvious decline with the EC value of not executing the soil conditioner before measurement, drops to 3.05ms/cm from 4.76ms./cm, and the plot pimento of relatively using soil conditioner with the contrast of not executing soil conditioner (other control measures are identical) increases production 25.1%.

Embodiment 4

Potassium humate 40

Zeyssatite 40
