Problems solved by technology

[0003] The problem of soil degradation in my country is serious, resulting in the reduction of crop yield and quality
In order to solve the obstacles of continuous cropping in the soil of vegetable greenhouses in rural my country from July to August, the conventional repair of the soil is still carried out by "rotating crops, resting seeds, exposing to rain and sun, and applying organic fertilizers". Lack, waste of land resources, reduced income of farmers

[0033] Prepare the soil for continuous cropping as follows

[0034] A. Add 210 parts of water to 30 parts of chrysanthemum, 25 parts of fig, 30 parts of tea fruit, 10 parts of jujube and 10 parts of licorice, soak for 0.8 hours, then stir at 60 rpm for 15 minutes, 120 ° C, 0.1 MPa , stirring at 60 rev / min for 8 hours;

[0035] B. Naturally ferment the material obtained in step A for 30 hours, stir at 60 rpm for 1.8 hours at 120°C, settle naturally for 60 hours, and filter with a 300-mesh filter;

[0036] C. In the filtrate obtained in step B, add citric acid whose quality is 0.05% of the filtrate quality, 80° C., under 0.2 MPa, stir at 60 rpm for 1.5 hours, and let stand at room temperature for 10 hours;

[0037] D. To the material obtained in step C, add 0.2% ethanol whose mass is that of the filtrate obtained in step B, and stir at 120° C. at 0.4 MPa at 60 rpm for 0.8 hours to obtain a biological preparation;

[0038] E, 30% of the biological agent in step D and 70% of the...

Embodiment 2

[0042] Prepare the soil for continuous cropping as follows

[0043] A. Add 290 parts of water to 35 parts of chrysanthemum, 15 parts of fig, 35 parts of tea fruit, 5 parts of jujube and 5 parts of licorice, soak for 1.5 hours, then stir at 60 rpm for 15 minutes, 80 ° C, 0.4 MPa , stirring at 60 rev / min for 3 hours;

[0044] B. Naturally ferment the material obtained in step A for 55 hours, stir at 75 rpm for 2.8 hours at 80°C, settle naturally for 40 hours, and filter with a 300-mesh filter;

[0045] C. In the filtrate obtained in step B, add citric acid whose mass is 0.1%% of the filtrate mass, stir at 120°C and 0.2MPa at 60 rpm for 2.5 hours, let stand at room temperature for 15 hours, and then use 350 mesh The filter screen removes large particles;

[0046] D. To the filtrate obtained in step C, add 0.1% ethanol whose mass is that of the filtrate obtained in step B, and stir at 80°C and 0.6 MPa at 60 rpm for 1.5 hours to obtain a biological preparation;

[0047] E, 50% o...

Embodiment 3

[0051] The soil continuous cropping guarantee ② was used as the raw material for the following tests.

[0052] 1. Sample Preparation

[0053] A. Soil sample preparation: Naturally air-dry the soil taken from the field (Yuhe Greenhouse Vegetable Base, Xiangcheng District, Suzhou City, Jiangsu Province) until the water content is 3%, remove sand, stones, sticks, weeds and other foreign objects, and put After the soil clods and aggregates are crushed, they are all passed through a 20-mesh sieve, mixed evenly and stored for later use.

[0054] B. Preparation of improved soil samples: 90 parts of the above-mentioned soil samples were mixed with 10 parts of soil continuous crop protection ②, the said parts are parts by mass, stirred evenly, and placed in a plastic beaker. Add a certain amount of distilled water to ensure that the mass content of water is 50% every day, and stir once a day. After reacting for 10 days, the material was taken out and dried until the mass content of ...

Abstract

The invention discloses soil continuous cropping protector and a preparation method and application thereof. The soil continuous cropping protector is made from, by weight percent, 30-50% of biological agent and 50-70% of silica solution. The biological agent is made from, by weight, 30-35 parts of chrysanthemum flower, 15-25 parts of fig, 30-35 parts of tea fruit, 5-10 parts of Chinese date, and 5-10 parts of licorice root. The silica solution is 35-45% in mass concentration, and 3.0-3.4 in modulus. The silica solution enables massively accumulated heavy metals in soil, such as cadmium, mercury, lead and arsenic, to be nonionic by replacement reaction, and pollution of crops by the heavy metals in the soil is eliminated or relieved. By the soil continuous cropping protector, soil quartz structure is changed, acid-base balance of the soil is corrected, soil basicity is improved, disintegration of organic fertilizers is promoted, soil pathogenic bacteria are inhibited, and the problems of soil continuous cropping obstacles and the like are solved basically.

Description

technical field [0001] The invention relates to a soil continuous crop protection, its preparation method and application. Background technique [0002] For a long time, in order to increase agricultural production and income, chemical fertilizers have been used in the soil for a long time, resulting in the decline of soil fertility, the lack of organic matter, and the decrease of soil air permeability. Changes in the soil structure will cause soil compaction and soil continuous cropping obstacles; after continuous cropping of the same crop or related crops, under normal management, the aggravation of diseases and insect pests, secondary salinization and acidification of the soil, and imbalance of nutrients will hinder the growth of crops , poor fertility status. Yield decreases and quality deteriorates. [0003] The problem of soil degradation in our country is serious, resulting in the reduction of crop yield and quality. In order to solve the obstacles of soil continuo...
