High-yield Cultivation Method of Grafting Watermelon Field and Large Seedlings for Saving Plants

Abstract

The invention discloses a high-yield cultivation method for grafting large seedlings of watermelon in a large field, which comprises four production steps of grafting large seedlings, growing seedlings from seedlings, multiplying vines and multiplying fruits, and changing stubble in continuous cropping. The core of the present invention lies in a major breakthrough in grafting technology, that is, rootstock grafting is carried out from the traditional cotyledon stage to the group tree stage, and the scions are taken from the side vines of the first batch or previous watermelon grafted seedlings, and the seedlings are used to grow seedlings, which saves a lot of money. Quantity. Compared with the traditional watermelon cultivation and seedling grafting, the present invention has obvious advantages, the grafting is easy to operate, has a high survival rate, can be carried out directly in the field without facilities, reduces costs, is convenient for management, does not need hardening, can grow seedlings 20 days earlier, and grows quickly. The fruiting ability is strong, and the quality has no effect; usually, the yield per mu in a single season is 4000-6000 kg, and the continuous cropping in three seasons can reach more than 12000 kg. The invention is particularly suitable for large-area continuous cropping cultivation of watermelon and large-scale intensive high-quality graft seedling cultivation. The invention can also be widely applied to melon vegetable crops, and promotes general improvement of their quality, and the melons are delicious and cheap.

Description

technical field [0001] The invention relates to a method for grafting watermelons, in particular to a method for grafting large watermelon seedlings to save species and high yield, and belongs to the field of agricultural production. Background technique [0002] Before the disclosure of the present invention, the large seedling grafting and seedling raising method had not yet appeared in watermelon seedling raising. Watermelon juice is sweet, fine and cool, and refreshing to eat. It is a good product for relieving heat and thirst in summer, which is favored by consumers. my country is the country with the largest watermelon cultivation area and the largest output in the world, with an annual area of ​​more than 20 million mu. Cultivating high-quality watermelon seedlings is an important basis and premise for achieving high yield and high quality in cultivation management. Traditional watermelon seedling cultivation mainly adopts live seedling cultivation, but there are sh...

AI Technical Summary

Problems solved by technology

Traditional watermelon seedling cultivation mainly adopts live seedling cultivation, but there are shortcomings such as long seedling time, large amount of seeds required, poor quality, and inability to continue cropping; It is necessary to sow a watermelon seed to cultivate a small seedling as a scion, and after indoor grafting, outdoor seedling cultivation is required. There are still problems such as large amount of seedlings, inconvenient operation of small seedling grafting, high difficulty, low survival rate, and long time for seedling cultivation. The high-quality watermelon seeds are expensive, the production cost is high, and it is difficult to adapt to large-scale supply of seedlings, resulting in the high market price of high-quality watermelons.
