Sweet potato leaf planting method

Abstract

The invention provides a sweet potato leaf planting method. The method comprises the steps of 1) domesticating mixed earthworms; 2) arranging planting lands, and spreading the domesticated mixed earthworms into the soil of a greenhouse; 3) placing sweet potato seedlings in mixing liquid composed of, by weight, 2-3 parts of coarse salt, 1-2 parts of garlic, 2-3 parts of bitter leaf juice and 100-120 parts of water for soaking for 8-10 minutes, taking out, and drying; 4) inserting the sweet potato seedlings; 5) applying an organic fertilizer once on the 15th day after inserting, wherein the organic fertilizer is fermented from, by weight, 10-15 parts of a rotten fruit, 15-25 parts of discarded leaves, 10-15 parts of stigmata maydis, 10-20 parts of water hyacinth, 5-8 parts of broken egg shells, 5-10 parts of clay carbon, 3-5 parts of a rice bran, 5-10 parts of lactobacillus plantarum and 5-10 parts of bacillus bacillus liquid; 6) leaving 2-3 internodes on a base during picking, and applying the organic fertilizer in the next day after picking. The method can reduce the continuous cropping obstacle of the sweet potato leaf planting, prolong the rotation time and increase the yield andquality of sweet potato leaves.

Description

technical field [0001] The invention relates to the technical field of agricultural planting. More specifically, the present invention relates to a method for planting sweet potato leaves. Background technique [0002] In recent years, the use of greenhouses to grow vegetables can be marketed regardless of seasons, and annual production can greatly increase farmers' income. However, the problem of continuous cropping obstacles is often more prominent than that of vegetables grown in the open field. Sweet potato leaf planting is one-time planting and multiple harvesting. Vegetables, the use of traditional crop rotation to overcome continuous cropping obstacles is not conducive to the production of sweet potato leaves. There are three main aspects of continuous cropping obstacles: 1. Increased pest damage; 2. Soil salinization and acidification; 3. Uneven distribution of soil nutrients. Improving continuous cropping obstacles through pesticides and chemical methods is likely...

Problems solved by technology

Improving continuous cropping obstacles through pesticides and chemical methods is likely to cause harm to the soil, which is not conducive to the production of pollution-free, green and organic food

[0003] And sweet potato seedlings are a kind of plant that is easily infected with diseases and insect pests repeatedly and spreads quickly. Although the pests and diseases can be quickly eliminated by spraying pesticides, the growth cycle of sweet potato seedlings is short. Wait until the efficacy period has passed before picking. Some leaves are prone to aging or insect bites, which will affect the taste and appearance. If picked in advance, pesticide residues will easily appear
