Problems solved by technology

In the production practice of seedling budding technology, due to the influence of factors such as the quality of bud strips, the way of cutting stems, cultivation management measures and external conditions, the germination rate is unstable, the germination period is long, and the average proportion of non-germination is 8.5%. At that time, the non-germination rate could reach more than 30%, which affected the uniformity of seedling growth and the rate of nursery emergence
Huang Shoufeng, Lin Weifu, Xie Guishui and others conducted research on the method of promoting the germination of rubber tree seedlings, analyzed the factors affecting the germination of rubber tree seedlings, and reached a preliminary conclusion. For the effect of seedling budding, a formula with 6-BA as the main active ingredient has also been given, but it has not been popularized and applied in production.

Embodiment Construction

[0012] The present invention will be further described below with embodiment.

[0013] 1. Rootstock and bud strips

[0014] The rootstock is the germination seedling that has been germinated in the sand bed. About 2 to 3 weeks after sowing, the seedling grows vigorously, with a stem height of 15 to 30 cm, and is in the stage of elongation to leaf expansion. The buds are all green buds. It is recommended to use small green buds produced by professional multiplication nurseries, and the finer branches of conventional multiplication nurseries and certified tissue culture buds can also be used.

[0015] 2. Budding and planting of budding seedlings

[0016] Use the conventional seedling budding method, and try to handle it gently during the budding process to protect the rootstock seeds and avoid mechanical damage. The budded seedlings are planted straight and back in the center of the seedling bag, and the depth of the planting soil surface is even with the junction of the seedl...

Abstract

The invention discloses a method for promoting budding of seedling budlings of Brazil rubber trees. The method comprises the following steps of: topping pretreatment of seedling budlings, toping and bud removal for tree stock, budding promoter application to bud slices and culturing of strong seedlings. The method is simple in process flow and low in production cost, has no adverse effect on growth of seedlings, well promotes the budding effect, is stable in field performance, better solves the problems of slow budding and uneven budding of seedling budlings of Brazil rubber trees, is applicable to seedling budlings of Brazil rubber trees, which are grafted with buds and overwinter with apical buds left, lays a foundation for popularization of industrial seedling culturing of rubber trees.

Description

technical field [0001] The invention relates to a method for promoting sprouting of rubber tree seedlings, which belongs to the technical field of crop cultivation. Background technique [0002] Rubber tree seedling budding technology is the main technical means adopted in the factory breeding of rubber trees. This technology has a short seedling period, high land utilization rate, and effectively reduces the cost of materials and labor. It is the main technology currently promoted. In the production practice of seedling budding technology, due to the influence of factors such as the quality of bud strips, the way of cutting stems, cultivation management measures and external conditions, the germination rate is unstable, the germination period is long, and the average proportion of non-germination is 8.5%. At that time, the non-germination rate could reach more than 30%, which affected the uniformity of seedling growth and the rate of nursery emergence. Huang Shoufeng, Lin ...
