Abstract
The invention discloses a passion fruit high-position grafting breeding and planting method, and belongs to the field of passion fruit grafting and planting. The invention discloses a method for high-position grafting, breeding and planting passion fruit, which comprises the following steps: (1) selecting rootstock seeds; (2) seedling culture of the rootstock; (3) treating the rootstock; (4) selecting and grafting scions; (5) sterilization treatment after grafting; (6) planting management after grafting; (7) and (5) pest control management. The method adopts high-position grafting which is different from the traditional low-position grafting and is combined with the fruit hanging bunch, so that stem rot can be effectively prevented, the morbidity of the stem rot is reduced, and the yield of the grafted passion fruit is improved.
Description
Technical Field
The invention belongs to the field of passion fruit grafting and planting, and particularly relates to a passion fruit high-position grafting breeding and planting method.
Background
At present, an important factor restricting the production of the passion fruit is the wide spread of the stem rot of the passion fruit.
The parts damaged by the passion fruit stem basal rot are mainly plant stem basal parts 5-10 cm away from the ground, and both seedlings and adult plants can get ill. The seedlings are infected with diseases, the plants wither, leaves fall off and fade, and then the whole seedlings die; the adult plant is infected, in the early stage of disease attack, dark brown disease spots appear at the base of a plant stem, then the cortex of the diseased part becomes soft, cracks and rot appear, the epidermis is easy to separate, and under the condition of higher humidity, pink mildew appears on the surface of the diseased bark. Basal lesions gradually spread laterally around the stem, while some healthy epidermis remains if the basal lesions do not encircle the stem for up to one week, overground parts show withering and chlorosis of the leaves, and when adverse disease development under environmental and climatic conditions, the plants continue to survive for the next growing season, but with severe impact on yield and quality. If the disease spots at the base of the stem extend around the stem for one week, the leaves and the branches at the upper part will wither and yellow, then the whole plant will wither and die, the climatic conditions are more suitable for the diseased season, and the time from the withering to the death of the vines of the plant is shorter.
The traditional passion fruit stock grafting technology is characterized in that stock is grown to 15-20 cm and is subjected to low-position grafting, and the low-position grafting has the following problems: grafted seedlings are susceptible to stem rot, and the growth and yield are influenced by the occurrence of stem rot. The low-position grafting is easy to infect the underground germs, and the pollination process is also easy to infect the low-position easily underground germs to cause the stem base rot.
The method has the advantages that the incidence peak of the passion fruit stem basal rot is in a high-temperature and high-humidity season of 5-7 months, the incidence rate is generally 20-30%, the serious land is more than 50%, the infectivity is strong, the spread is rapid in an orchard, the orchard is seriously short of plants, and the yield per unit area is reduced. The passion fruit plantation is serious in diseases such as high humidity, poor soil permeability, poor drainage, acidification and poor light transmittance.
Disclosure of Invention
The invention aims to provide a passion fruit high-position grafting breeding and planting method, which adopts high-position grafting different from the traditional low-position grafting and is combined with a fruit hanging string, so that stem rot can be effectively prevented, the incidence of the stem rot is reduced, and the yield of the grafted passion fruit is increased.
The purpose of the invention is realized by the following technical scheme:
a method for high-position grafting, breeding and planting passion fruit comprises the following steps:
(1) selecting rootstock seeds: soaking seeds of golden fruit seedlings without mildew, diseases and insect pests in water for 20-30 hours, removing the seeds floating on the water, fishing out the rest seeds, flatly paving the seeds in a germination accelerating box with constant temperature and humidity, spraying 800-1000 times of methyl mop body fluid, and then accelerating germination to obtain naturally cracked seeds;
(2) seedling culture of the rootstock: the seedling bed adopts perlite matrix, and the perlite matrix is sprayed with aerial fog in advance to keep the humidity in the matrix at 50-80%; digging a pit with the depth of 1-3cm in the substrate, sowing the naturally cracked stock seeds with the opening facing downwards, and cultivating the seeds by adopting an aerosol spraying method after sowing;
(3) and (3) treating the rootstock: selecting golden fruit seedling stock seedlings which are free of plant diseases and insect pests and have healthy growth conditions, culturing to 90-100cm, cutting off the stock when the golden fruit seedling stock seedlings grow to a height of 70-80cm, and removing all other lateral branches; sterilizing and disinfecting the rootstock by using 800-1000 times of methyl mop body fluid;
(4) selecting and grafting scions: selecting passion fruit plants which are free of diseases and insect pests, healthy in growth condition, high in yield and excellent in quality, selecting healthy seed buds which are full in bud points, dark green in leaf color and free of diseases and insect pests or passion fruit seedlings with the height of more than 5cm as scion seedlings, and grafting by adopting a cutting and grafting method; after the grafting survives, performing normal water and fertilizer management, and planting by using a conventional shed building frame; in the step, the passion fruit seedlings can adopt the passion fruit plants of other excellent varieties as scions;
(5) and (3) sterilization treatment after grafting: performing primary preservative treatment on the roots of the passion fruits 30 days after grafting and 60 days after grafting respectively, and spraying preservative agents on the roots of the passion fruits, wherein the stems are wet;
(6) and (3) management after grafting: adopting a conventional grafting planting management mode, when the branches bear fruits on the shed frame, hanging the branches bearing the fruits on the shed downwards, and cutting off the tops when 4-6 fruits bear on the branches; the fruit shed is ventilated, and sunlight shines downwards, so that fruits are prevented from being clamped in fruit leaves on the shed, the comprehensive utilization space is improved, and the utilization rate of a fruit shed frame is improved;
