Full-illumination rapid cuttage propagation method of melon tree

Abstract

The invention relates to a papaya full exposure fast cutting propagation method, characterized in that, hermaphrodite carica papaya tree is used as female parent, an upper part of the tree is cut from the lowest part, then the female parent is stubbed and transported to a field gene bank, a root part is processed by radication agent containing 6-benzyl adenine 0.05-0.2 mg, indolebutyric acid 0.5-1.0 mg per liter; a tree body is sprayed with polysulfide suspending agent and bud advancing agent containing 6-benzyl adenine 5.0-10.0 mg and triiodobenzoic acid 0.5-1.0 mg, causing a parent tree to come out lateral buds, mowing down the lateral buds as root taking agent soaked for cutting shoot; a base part is bedaubed with rootone containing naphthylacetic acid 50-100 mg and indolebutyric acid 100-200 mg per kilogram, inserted to a planting screen, transplanting to the nutrient cup after the shoot to be inserted comes out adventitious roots and new leaves, then permanently planted in the field. The invention is small in investment, short in time, tree percent is more than 80%, root taking rate and survival rate reach more than 85%, thereby providing effective approach for meeting with the requirement of the germchit market.

Description

technical field [0001] The invention relates to a propagation method of papaya, in particular to a rapid cutting propagation method of papaya (Carica papaya) under full light. Background technique [0002] Papaya is known as "Lingnan Fruit King". Papaya is easy to cultivate, bears fruit early, has high yield, is full of treasures, and has a wide range of uses. Fruit-type papaya has become the darling of the market because of its good fruit shape and delicious taste. The demand in the domestic market is predicted to reach 200,000 tons per year, and the output value is about 300 million yuan. Therefore, the planting area of ​​fruit-type papaya should be 5 More than 10,000 mu, about 5,000,000 hermaphrodite seedlings with stable plant sex are needed every year. [0003] Papaya can be propagated sexually by seeds and by cuttings, grafting, and asexually by tissue culture. The fruit type and quality of different papaya plants are different, and the offspring produced by seed pr...

AI Technical Summary

Problems solved by technology

The fruit type and quality of different papaya plants are different, and the offspring produced by seed propagation from the same papaya plant will have separation, so it is difficult to achieve the production goals of high-quality, high-yield, and high-efficiency papaya in seed propagation

In order to obtain a higher ratio of oblong hermaphrodites with higher commercial value, traditional planting uses 2 to 3 seedlings in each planting hole, and when the plants bloom and the flower sex can be distinguished, the hermaphrodites are left, and the rest are cut off. , but sometimes there are no hermaphroditic plants among the 2-3 seedlings in the same hole, so this planting method not only increases the cost of seedlings and seedling management, but also affects the field growth of papaya

The papaya grafting and propagation process is complicated and the tissue culture is difficult. In 1964, Allan et al. used papaya side branches to propagate cuttings into cutting seedlings, and they could obtain seedlings of the same gender as the original ear-picking mother plants. Low, unable to meet the needs of commercial cultivation
