Problems solved by technology

2. Deterioration of the soil leads to a decrease in the activity of soil microorganisms and a decrease in the decomposition of nutrients; the activity of crop enzymes decreases, cell division slows down, and the membrane structure is destroyed, thus affecting the absorption and transportation of mineral elements
3. Soil salinity and PH imbalance will increase with the extension of cultivation years, and gradually accumulate to the surface layer, resulting in surface soil compaction, physical and chemical deterioration, and PH value increase, affecting the absorption of nutrients by crops
[0003] Therefore, in the current planting of pinellia, the continuous cropping is more harmful, resulting in soil rotation and recovery, and the utilization rate is not high, which increases the labor of pinellia planting, which is not conducive to the large-scale production of pinellia.

Embodiment 1

[0016] A soil ecological improvement method for cultivated pinellia, comprising the following steps:

[0017] (1) Earthworm cultivation: after pinellia harvest, use potassium permanganate dilution to irrigate the soil, cover the soil with mulch film for 3 days, then uncover the mulch film; plow the soil 40cm deep, use earthworm inoculum according to 300kg / mu, and The soil is shallowly plowed 20cm, and it can be cultivated for a week;

[0018] The preparation method of the potassium permanganate dilution is as follows: in terms of mass points, 1 part of potassium permanganate is mixed with 800 parts of clear water and dissolved at 60 ° C to obtain the product, and the usage amount is 60 kg / mu. The spraying temperature of the diluent is 45-50°C;

[0019] The preparation method of the earthworm inoculum is as follows: in terms of mass points, 80 parts of undecomposed horse manure, 20 parts of corn stalk powder, 30 parts of rapeseed, 15 parts of rapeseed meal, and 10 parts of pin...

Embodiment 2

[0024] A soil ecological improvement method for cultivated pinellia, comprising the following steps:

[0025] (1) Earthworm cultivation: after pinellia harvest, use potassium permanganate dilution to irrigate the soil, cover the soil with mulch film for 5 days, then uncover the mulch film; turn the soil 50cm deep, use earthworm inoculum according to 400kg / mu, put The soil is shallowly plowed 30cm, and it can be cultivated for a week;

[0026] The preparation method of the potassium permanganate dilution is as follows: in terms of mass points, 3 parts of potassium permanganate and 900 parts of clear water are mixed and dissolved at 65° C., and the usage amount is 80 kg / mu. The spraying temperature of the diluent is 50°C;

[0027] The preparation method of the earthworm inoculum is as follows: in mass points, 100 parts of undecomposed horse manure, 30 parts of corn stalk powder, 40 parts of rapeseed, 35 parts of rapeseed meal, 20 parts of pine needle powder are mixed evenly, an...

experiment example

[0041] The technical solutions of the present invention will be further limited below in conjunction with specific embodiments, but the scope of protection is not limited to the descriptions made.

[0042] In the Pinellia planting base, 4 mu of plantations that had been planted Pinellia continuously for three years were randomly divided into 4 groups, namely experimental group 1, 2 and control group 1, 2; Control group 3. Experimental groups 1, 2 and control groups 1, 2 were treated according to Examples 1, 2 and Comparative Examples 1, 2, respectively, and then in March 2016, Pinellia were uniformly planted, and the five groups were planted with locally preferred Pinellia, using the same After harvesting, the yield and quality of pinellia were measured, and the soil microbial content was tested.

[0043] Experimental effect:

[0044]

[0045] It can be seen from the table that Pinelliae planted by the method of the embodiment of the present invention is better than the c...

Abstract

The invention relates to the technical field of planting and particularly relates to a method for ecological improvement of pinellia ternata cultivation soil, comprising the following steps of sputumculture and green manure planting. The method of the invention can effectively kill the pathogenic microorganisms produced in the continuous cropping of pinellia ternata, regulate the soil biocenosis,accelerate the material circulation in the soil, inhibit the propagation of the soil-borne pathogenic microorganisms in the subsequent planting, and degrade the autotoxicity generated in the growth of pinellia ternate, so as to accelerate the formation of benign soil ecology after the continuous cropping of pinellia ternata.

Description

technical field [0001] The invention relates to the technical field of planting, in particular to a soil ecological improvement method for cultivating Pinellia pinellia. Background technique [0002] Pinellia is a high-value Chinese herbal medicine with low requirements on the living environment. It is widely distributed all over the country and grows below 2,500 meters above sea level. It is often found on grass slopes, wasteland, corn fields, beside fields or under sparse forests. Planted pinellia is the main source of income in many places. However, pinellia tends to release toxic components during its growth, causing the compositional structure of the soil to be out of balance and affecting the planting and production in the next season. The main impacts of continuous cropping pinellia on the soil are as follows: 1. The accumulation of pathogenic bacteria is serious, and the occurrence of diseases and insect pests is frequent and gradually aggravated. In particular, so...
