AI Technical Summary

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

Abstract

The invention provides a method for planting sweet potato leaves, comprising the steps of: 1) domesticating mixed earthworms; 2) planting site arrangement: spreading the domesticated mixed earthworms on the soil in a greenhouse; 3) placing sweet potato seedlings in parts by mass of coarse Soak 2-3 parts of salt, 1-2 parts of minced garlic, 2-3 parts of neem leaf juice and 100-120 parts of water for 8-10 minutes, take it out and dry; 4) plant sweet potato seedlings; 5 ) on the 15th day after planting, the organic fertilizer is applied once, and the organic fertilizer is fermented from the following raw materials in parts by weight: 10-15 parts of rotten fruit, 15-25 parts of discarded vegetable leaves, 10-15 parts of corn silk, water hyacinth 10‑20 parts, 5‑8 parts of broken egg shells, 5‑10 parts of peat, 3‑5 parts of rice bran, 5‑10 parts of plantaractobacillus agent and 5‑10 parts of bacillus liquid; 2-3 internodes, spread the organic fertilizer on the second day after picking. The invention can reduce the continuous cropping obstacle of sweet potato leaf planting, prolong the crop rotation time, and improve the output and quality 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...
