Embodiment 1

[0016] Select 800 fresh and plump rubber tree seeds harvested in August and sow them on the sand bed to accelerate germination and cultivate them for 15 days. Select 400 strong seedlings with a height of about 4cm, pull them out together with the seeds, wash them with clean water, and use a budding knife to put embryos on the seedlings. The top of the shaft 3 is repeatedly cross-cut to let the latex flow out until no latex flows out, and put it aside for future use.

[0017] 20 days before bud grafting, select the robust bud strips of rubber trees to be grafted; cut off the terminal buds of the bud strips to promote the sprouting of new shoots from the leaf buds; The small stem section of bud or side bud is used as scion 1, and is for subsequent use.

[0018] Make another cut at the incision at the top of the epicotyl 3 of the seedling, cut off the length of the end to be no more than 0.3 cm, then longitudinally cut a "one"-shaped opening along the widest section of the top of...

Embodiment 2

[0021] Select 500 fresh and plump rubber tree seeds harvested in September and sow them on the sand bed to accelerate germination and cultivate them for 18 days. Select 200 strong seedlings with a height of about 5 cm, pull them out together with the seeds, wash them with clean water, and use a budding knife to put embryos on the seedlings. The top of the shaft 3 is repeatedly cross-cut to let the latex flow out until no latex flows out, and put it aside for future use.

[0022] 25 days before bud grafting, select the robust bud strips of the rubber tree species to be grafted; cut off the terminal buds of the bud strips to promote the sprouting of new shoots from the leaf buds; The small stem section of bud or side bud is used as scion 1, and is for subsequent use.

[0023] Make another cut at the incision at the top of the epicotyl 3 of the seedling, cut off the length of the end not greater than 0.3cm, then longitudinally cut the "one"-shaped opening along the widest section...

Embodiment 3

[0026] Select 300 fresh and plump rubber tree seeds harvested in October and sow them on the sand bed to accelerate germination and cultivate them for 20 days. Select 100 robust seedlings with a height of about 6 cm, pull them out together with the seeds, wash them with clean water, and use a bud knife to germinate the seedlings. The top of the axis 3 is repeatedly cross-cut to let the latex flow out until no latex flows out, and put it aside for future use.

[0027] 28 days before bud grafting, select the robust bud strips of rubber trees to be grafted; cut off the terminal buds of the bud strips to promote the sprouting of new shoots from the leaf buds; select new shoots with a stem thickness equivalent to the stem of the seedlings, and cut out 5 cm long, with terminal buds Or the small stem section of lateral buds is used as scion 1 for subsequent use.

Abstract

The invention belongs to the technical field of nursery stock bud grafting, and particularly relates to a cuttage-grafting seedling raising method for rubber trees. Rubber tree seeds are selected to be sowed and cultivated into seedlings according to a traditional cultivation mode; terminal buds of strong budlings to be used as cion varieties are removed, novel tops with stem diameters equivalent to the diameter of seedlings (stocks) epicotyls are cultivated to serve as cions for spare; the seedlings and the seeds are pulled out together, part of tops of seedling epicotyls is cut off transversely and repeatedly till no latex is discharged, and an opening is longitudinally cut at a top end section widest position of each of the seedling epicotyls; basal ends of small cut stems are whittled into wedge shapes, and the whittled stems are inserted into cuts at the top ends of the seedling epicotyls and bound; and cuttage-grafting seedlings are planted in seedling raising containers in glasshouses or greenhouses and cultivated according to a conventional seedling raising managing method after the cuttage-grafting. According to the cuttage-grafting seedling raising method for rubber trees, the operation is simple, the mode that small stems are grafted on the seedling epicotyls is utilized, so that grafting operation processes are simplified effectively, the stock budding number is reduced, and the cion budding efficiency is improved, the seedling raising time is shortened, and basic theories and methods are provided for the factory grafting and seedling braising of rubber trees.

Description

technical field [0001] The invention belongs to the technical field of seedling bud grafting, in particular to a rubber tree seedling raising method. Background technique [0002] The rubber tree is native to the western part of the Mara Mountain in the Amazon River Basin of Brazil. It is an evergreen tree and is suitable for the growth of acidic sandy loam with thick, fertile and moist soil and good drainage. The rubber planting areas in my country are mainly distributed in Hainan, Yunnan, and Guangdong. , Guangxi, and Fujian, among which Hainan is the main rubber planting area. The rubber products made from the latex of the rubber tree have strong elasticity and good insulation, plasticity, water-proof and gas-proof properties. Tensile and wear-resistant characteristics, widely used in industry, national defense, transportation, medical and health fields and daily life. [0003] At present, the commonly used budding seedling raising method of rubber tree is patch budding ...
