Standardized grafting seedling raising method for high-sweetness small watermelons

Abstract

The invention discloses a high-sweetness small watermelon standardized grafting seedling raising method which comprises the following steps: 1, site selection and construction, 2, facility and equipment disinfection: performing spray disinfection on a seedling raising greenhouse, a greenhouse film, a seedling bed, a seedling raising tray and the like; 3, selecting and preparing a substrate, and loading the substrate into a tray, namely uniformly pouring the substrate into a seedling raising tray, shaking the seedling raising tray to enable the substrate to be compactly filled in seedling raising holes, then compacting and scraping the substrate on the surface of the seedling raising tray by using a small wood plate with the thickness of 1cm and the length of 50cm, and then compacting and scraping the substrate on the surface of the seedling raising tray by using a small wood plate with the thickness of 1cm and the length of 50cm; 4, stock cultivation; 5, scion cultivation; 6, preparation before grafting; 7, grafting; the method has the advantages that grafted seedlings cultivated through the method are robust, neat and consistent, developed in root system, high in water absorption and fertilizer absorption capacity, rapid in seedling recovery after field planting, robust in growth and development and not prone to premature senility.

Description

technical field [0001] The invention relates to a watermelon seedling raising method, in particular to a standardized grafting seedling raising method for small watermelon with high sweetness. Background technique [0002] The annual sown area of ​​watermelon in my country is 2.22 million hectares, with an annual output of 53.86 million tons, accounting for 60% of the world's watermelon cultivation area and total output, ranking first in the world in sown area and output. [0003] With the continuous increase of the sown area, people's interest in large watermelons is decreasing day by day, and more and more farmers choose to grow small watermelons. The normal growth of watermelon plants, resulting in reduced yield and quality, has seriously hindered the development of the watermelon industry. Grafting and raising seedlings have high requirements on grafting technology, environmental conditions and management measures. The grafting method in the current technology is not ef...

Problems solved by technology

[0003] With the continuous increase of planting area, people's interest in large watermelon is decreasing day by day, and more and more farmers choose to plant small watermelon. The normal growth of watermelon plants leads to lower yield and lower quality, which seriously hinders the development of watermelon industry

Grafting seedlings have high requirements on grafting technology, environmental conditions and management measures. The grafting method in the current technology is not efficient, and there are problems such as high morbidity, low survival rate and weak growth of grafted seedlings. Therefore, people have been looking for solutions
