Description

Melon net climbing type cultivation method

Technical Field

The invention relates to the technical field of agricultural planting, in particular to a melon net climbing type cultivation method.

Background

The frame body of monomer arch big-arch shelter can not bear the weight of melon tendrils and its fruit, and ground climbing formula is adopted mostly to cultivate melon, and ground climbing formula cultivation melon has two deficiencies: firstly, because the melon vines and fruits thereof are tightly attached to the ground, the air fluidity is low, the air humidity is high, the bacterial soft rot and downy mildew diseases are relatively serious, the disease prevention and medication are correspondingly more, and the internal quality of the fruits is influenced; secondly, the side of the fruit close to the ground is not illuminated, the whole coloring is not good, the selling is poor, and the market sale is influenced.

The melons are cultivated in the sunlight greenhouse, tendril hanging cultivation is adopted, the two problems of insufficient cultivation of the melons in ground climbing are effectively solved, the cultivation density of the melons can be increased by 50%, and the quality improvement, the yield increase and the effect improvement are obvious. Sunlight greenhouses have two disadvantages: firstly, the indoor site is inconvenient to move, and the continuous cropping obstacle problem is serious; secondly, the one-time investment is huge, the solar greenhouse occupation ratio is not high in economically undeveloped areas, and the application of the vine-hanging melon cultivation technology is influenced.
