Standardized seedling raising method of Jinggang honey pomelo

Abstract

The invention belongs the technical field of seedling raising, and discloses a standardized seedling raising method of Jinggang honey pomelo. The method comprises the steps that a nursery can be locally leveled to be used for seedling raising; according to volume, 40% of decomposed organic fertilizer, 18% of plain loess, 30% of rice hull ash, 10% of rice hull and 2% of calcium magnesium phosphor are used; black plastic film bags are selected to be seedling raising containers; bagging and substrate bagging can be carried out by an improved machine or manual work; substrates are placed orderly on a rectangular piece of land after being bagged; rootstock planting is carried out, wherein one Jinggang honey pomelo is planted in each bag, and watering for root fixing is carried out in time afterplanting is completed; after buds of scions are germinated, grafting film is unfastened in time, and sprout tillers on rootstocks are removed timely. The standardized seedling raising method of Jinggang honey pomelo has the advantages that the growth of weeds and occurrence of diseases and pests can be controlled, so that the pesticide applying frequency can be reduced; the seedling raising substrate is optimized, and the outplanting standard is improved, so that early bearing and high yield are achieved; the seedling raising containers are improved to save the planting cost; transplanting with soil is achieved, so that and survival rate is improved; the operability is high; the cultivated land soil is protected, so that soil organic materials are prevented from losing.

Description

technical field [0001] The invention belongs to the technical field of seedling cultivation, and in particular relates to a standardized seedling cultivation method of Jinggang honey pomelo. Background technique [0002] On the basis of the existing Jinggang honey pomelo seedling raising methods and agricultural facilities, the integration of plastic film container bag substrate seedling raising technology has been developed. Using the proportioning substrate instead of cultivated land soil, improving seedling raising containers, bagging machinery and integrated water and fertilizer facilities, Jinggang honey pomelo rootstocks are grafted in plastic film container bags until they are sold out of the nursery. It can well solve the problems of difficulty in weed control and high labor cost in Jinggang honey pomelo seedlings raised in open field; In the sapling stage, achieve early knot and high yield. There are two existing methods for breeding Jinggang pomelo seedlings: one...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the existing problems in the prior art are: open-field seedlings have high requirements for seedling fields, and fields with fertile soil, high organic matter content, and smooth drainage and irrigation must be selected; open-field seedlings are difficult to control the growth of weeds, and the fertilizer utilization rate is low , the number of fertilization increases, which increases the production cost; the seedlings are not strong enough to be transplanted with soil, and the survival rate of planting is not high; fourth, the bagged fake planting requires secondary planting to increase the time cost, and the bagged soil ball is too large to waste arable land , increasing the transportation and planting costs of growers
