High-yield litchi cltivation method including grafting one-year old saping and bearing fruits in two years after grafting

Abstract

The cultivation method for litchi includes the measures and steps of selection of orchard, selection of sapling, application of sufficient base fertilizer, rational close-planting, rational fertilizer application, rational topiary work and lopping, prevention and control of diseases and pests, promoting blooming through branch control, maintaining flowers and fruits, and treatment after picking. The said method for litchi annotinous grafted sapling and and two-year fructification is simple practical and suitable for litchi cultivation.

Description

technical field [0001] The invention relates to a method for cultivating fruit trees. Background technique [0002] In the novelty search report commissioned by the applicant to the Guangdong Institute of Science and Technology Information, completed on June 7, 1999 and numbered 990462 in the scientific and technological information novelty search report: "Huaizhi litchi dwarfing dense planting early fruiting and high yield Cultivation technology research "Chinese Fruit Trees" 1994.1.P1" is the Guangdong Academy of Agricultural Sciences since 1982, using Huaizhi varieties as test materials to conduct comprehensive technology research on dwarf dense planting, early fruiting and high yield, and the results of three years of planting.

Problems solved by technology

[0004] In the past, the field selection, seedling selection, field planting and management of litchi cultivation methods were unreasonable, resulting in extensive field planting, low survival rate, slow growth rate, uneven growth, four years of field planting to bear fruit, and low yield.

[0005] The existing lychee cultivation methods mostly choose mountainous areas without water and electricity, do not pay attention to water and soil conservation, the soil is easy to harden, and the air permeability is poor. In case of moderate torrential rain, large soil erosion or water accumulation in fruit holes will cause seedlings to rot and affect seedlings. Growth; the seedlings are transplanted and grafted seedlings cultivated in laterite sandy soil for two years. The root system is underdeveloped, and the survival rate of field planting is low, only about 70%. The plant row spacing is 6m x 5m, each 666.7M 2 Plant 30 to 40 plants, set holes and make pits of 0.8m x 0.6m (width x depth), add phosphorus fertilizer to each hole, mix soil miscellaneous fertilizer, soil skin and soil, and then plant seedlings, so the garden has not undergone deep plowing to improve the soil. Poor soil porosity, air permeability and drainage, insufficient basal fertilizer, are not conducive to the rapid growth of fruit seedlings, and the planting is sparse, which makes it difficult to produce high yields; fertilization is partial to chemical fertilizers, pig and cow manure, soil miscellaneous fertilizers, young trees are fertilized, winter fertilizers, and pre-flowering fertilizers Insufficient fertilization, strong fruit fertilizer, and pre-harvest fertilizer are unreasonable, so that the fruit trees cannot grow quickly and yield early. High yield; the prevention and control of diseases and insect pests is not paid enough attention, spraying pesticides only when serious pests and diseases are found, affecting the rapid growth of fruit trees, fruit borers often occur, affecting fruit quality; spraying ethephon or paclobutrazol to control shoots and promote flowers, improper spraying of ethephon will cause fruit trees yellow leaves, effect

[0006] Growth potential: Spraying regulators such as Guoteling or anti-falling agent for flower and fruit preservation, the effect is not good enough
