Method for producing seedless watermelon seedlings

Abstract

The invention discloses a method for producing seedless watermelon seedlings, which comprises the following steps: A) taking source branches and tendrils; B) selecting grafting time; C) adopting two grafting methods of close-joining and inoculation; and D) carrying out management after grafting: (1) temperature management; (2) humidity management; (3) light radiation; (4) timely excision of buds; and (5) disease control, pest control and hardening of the seedlings. The method is characterized by utilizing the strong branchiness of seedless watermelons, cleverly combining the branches and the tendrils with the grafting technology, carrying out clonal rapid propagation of the seedless watermelons and breaking through the traditional propagation technology of producing one watermelon seedling by using only one or a plurality of seeds; furthermore, the method has the advantages of easy and simple operation, high seedling rate, high propagation coefficient and reduced production cost of the seedless watermelons.

Description

technical field [0001] The invention belongs to the technical field of grafting and raising seedlings of melons and vegetables, and more specifically relates to a production method of seedless watermelon seedlings. It is suitable for grafting seedlings of melon crops (such as seeded watermelon, muskmelon, cucumber and bitter gourd, etc.) as scions and gourds as rootstocks. Background technique [0002] The fruit of seedless watermelon has no seeds, good quality, convenient eating, high yield and disease resistance, and storage and transportation resistance. It is popular among producers, operators and consumers. The planting area is gradually expanding, and it is cultivated all over the country. At present, the seedless watermelon cultivated in production is triploid, which is a first-generation hybrid produced by crossing tetraploid watermelon as the female parent and diploid watermelon as the male parent. However, due to the difference in the number of chromosomes of the ...

Problems solved by technology

However, due to the difference in the number of chromosomes of the parents and the low affinity, the amount of seed collection is low; the seed coat of the triploid seeds is thick and hard, the hilum is wide and hard, the seed embryo is poorly developed, and the cotyledons are mostly irregularly bonded. Germination requirements The conditions are high, and the optimum temperature for germination is 32-35°C, which leads to low germination rate; the seeds germinate with strong respiration, large water absorption, high humidity, suitable oxygen content, insufficient seeds, insufficient nutrients stored in cotyledons, and weak top soil ability , resulting in a low seedling rate

Therefore, the cost increases in the seedless watermelon production process (as the price of the small seedless watermelon seeds sold on the existing market is just as high as 1.5 yuan / grain, and the price of some good quality seedless watermelon seeds is more expensive), resulting in the sale of seedless watermelons The corresponding increase in price discourages ordinary consumers and seriously restricts the healthy and rapid development of seedless watermelon
