Method for directly sowing melon and vegetable crops in farmland

Abstract

The invention discloses a method for directly sowing melon and vegetable crops in a farmland. A fundamental principle and method of a soilless substrate seedling transplantation technology are combined to an existing farmland direct sowing technology, the technical advantages of both the soilless substrate seedling transplantation technology and the existing farmland direct sowing technology are centralized and exceeded, the effect of "1+1>2" is realized, the method is simple and convenient to operate, easy to master, obvious in effect, reliable and stable, the direct production cost is between the cost of the soilless substrate seedling transplantation technology and the cost of the existing farmland direct sowing technology and is controllable and limited, the crop production and efficiency increasing effects are obvious, and the method is suitable for large-area production and application and has remarkably strong creativity, novelty and practicability. Compared with the existing farmland direct sowing technology, the method has the advantage that soilless seedling raising substrate soil is additionally added into sowing holes, and the advantages are mainly embodied in high emergence rate, high seedling percentage, strong seedlings, high resistance, high growth speed, early maturation and production increment.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a method for field direct seeding of melon and vegetable crops. Background technique [0002] The existing field direct seeding technology is very common in general melon and vegetable crops (such as watermelon, melon, cucumber, wax gourd, pumpkin and beans, etc.), and it is generally done in the field. Finally, a certain amount of seeds (or buds) are directly sown in the soil according to the planned plant spacing in the planting zone. After the seedlings are unearthed, thinning and strengthening field management are carried out in batches in stages. General melon and vegetable crops (such as watermelon, melon, cucumber, wax gourd, pumpkin, and beans, etc.) have many cultivation stubbles, and seedling cultivation and transplanting methods are commonly used in field cultivation at home and abroad, but in summer or high temperature weather (day temperature ≥ 33°C and night temperature ...

AI Technical Summary

Problems solved by technology

If the soil is compacted, the air permeability is poor, the soil moisture is heavy or insufficient, and the soil diseases and insect pests are obvious during direct seeding, the emergence rate will be low, or even if the seedlings emerge weakly, the growth will be slow; , it is prone to poor seedling emergence, dead seedlings, weak seedlings and slow seedlings

The root cause of this phenomenon is that the direct seeding soil cannot provide suitable growth conditions such as water, air and nutrients for seed germination and seedling growth, which will hinder the growth and development of the seedling root system and affect the normal growth.

[0004] Underdeveloped root system of direct-seeding seedlings, damage by diseases and insect pests, and stunted growth are the most fundamental reasons for problems in the seedling stage of common melon and vegetable crops (such as watermelon, melon, cucumber, wax gourd, pumpkin and beans, etc.) in the field direct-seeding technology. , thus greatly affecting the growth of crops in the later stage, resulting in a 30-50% yield reduction, or even 70% or no harvest
