Method for growing seedlings of pomelos

Abstract

The invention relates to a method for growing seedlings of pomelos. The method includes sequential steps of sowing seeds and cultivating rootstock; digging field planting pits; planting the rootstock seedlings in fields; carrying out grafting management. The method has the advantages that the method is high in pollination efficiency and seed collection quantity, early in seed collection time and good in stock-scion grafting compatibility, and the rootstock is high in disease resistance; shortcomings of low winter and spring temperatures, short illumination time, great humidity variation and insufficient soil nutrient supply can be overcome, and growth of the rootstock seedlings can be greatly accelerated; seedling recovering stages due to damage to root systems can be omitted, the growth density of plants is obviously lowered after the plants are planted in the fields, accordingly, tree growing spaces can be greatly increased, utilization of illumination, water and nutrients can be greatly improved, a large quantity of nutrition can be accumulated in trees, tips of branches can grow fast, trunk diameters and thicknesses can be quickly increased, grafting can be carried out in advance, tree forms can be formed early after the trees are grafted, flowering and fruit bearing can be shifted to an earlier time, and economic benefits can be realized quickly; organic fertilizers contain comprehensive and balanced nutritional components, accordingly, growth and development requirements of the pomelos can be met, and growth of the pomelos can be accelerated.

Description

technical field [0001] The invention relates to the technical field of pomelo seedling cultivation, in particular to a pomelo seedling cultivation method. Background technique [0002] Pomelo (Citrus grandis L.Osbeck), also known as throwing, Wendan, etc., is a plant of the genus Citrus (Citrus L.) in the family Rutaceae. The pomelo fruit is huge, the flesh is crystal clear, the flavor is unique, the aroma is pleasant, and the nutrition is rich. It is a good fresh food. Pomelo fruit not only contains sugar, organic acid, protein, minerals and other nutrients, but also rich in vitamin C and insulin-like, polyphenols, flavonoids, limonoids, carotenoids, coumarins, essential oils , dietary fiber and pectin and other biologically active substances, have anti-oxidation, hypoglycemic, hypolipidemic, weight loss, skin beautification, anti-cancer and other effects. Regular consumption has auxiliary therapeutic effects on hypertension, diabetes, arteriosclerosis and other diseases ...

AI Technical Summary

Problems solved by technology

When rootstock seedlings were transplanted and grafted seedlings were planted, measures such as cutting off some leaves, dipping the root system in yellow mud, and wrapping the root system with plastic film were taken. However, the root system of pomelo seedlings was inevitably damaged during the artificial seedling raising process, resulting in an imbalance in the water supply of pomelo seedlings. , the slow seedling period after planting is as long as 20 to 30 days, the sprouting of new shoots is delayed, the growth of shoots is small, the grafting time is delayed, the tree shape is formed late, the flowering and fruiting period is delayed, and the economic benefits are slow, which affects the fruit farmers to a certain extent. The enthusiasm for growing pomelo
