Method for burying birth control seedlings in sympodial bamboo

Abstract

The invention discloses a method for burying birth control seedlings in sympodial bamboo. The method comprises the following steps: (1) selection and soil preparation of a nursery field: deep plowing,leveling, setting a seedling bed as a ridge, disinfection treatment and sprinkling profoundly water; (2) selection of a bamboo seedling section: hewing down new bamboo, taking bamboo sections, and wrapping bamboo sections to obtain seedling bamboo sections; (3) earlier stage processing of the seedling bamboo sections: before seedling, drilling holes in the middle parts of the seedling bamboo sections, injecting a growth hormone solution, and sealing the holes; (4) seedling: forming a planting ditch in a seedling bed, enabling the drill holes of the bamboo sections to be upward, putting the bamboo sections into the planting ditch, earthing, compacting, sprinkling profoundly water, and coating the seedling bed with a film; (5) nursery field management: after bamboo seedlings come up out ofthe ground, opening the film at sprouting positions, watering and maintaining soil to be wetted; setting a shading net; clearing the film, and seeding; bagging for preventing frostbite; taking out theseedlings in early spring or late autumn of the next year. According to the method, the survival rate of bamboo seedlings can reach 55% at most, the breeding efficiency is high, the seedling cost islow, and the method is simple, convenient and easy for popularization.

Description

technical field [0001] The invention relates to a method for raising seedlings of clustered bamboos, in particular to a method for raising seedlings of medium and large clustered bamboos by burying them. Background technique [0002] Cluster bamboo is a kind of bamboo species with important economic value in the south. Its bamboo shoots are edible, bamboo wood can be used for pulp, fiber, splitting and weaving, and bamboo plants can be used for ornamental and greening. The propagation methods of clumping bamboo mainly include seedling raising with strings, seedlings with buried joints, and seedlings with cuttings. However, for large and medium-sized clustered bamboos, the cost of breeding with strings is high, the number is small, and the efficiency is low, while seedlings with buried joints and cuttings The reproductive survival rate is generally low, which can increase the survival rate of large and medium-sized clustered bamboo seedlings, improve the reproductive efficien...

Although this method has a high seedling survival rate, the seedling raising material is mother bamboo, which limits the amount of seedling raising materials

[0004] CN102523891A discloses a method for propagating seedlings of large clustered bamboos. The method adopts the traditional method of raising seedlings with a stalk, and when the new bamboo grows to the point where the 1 to 4 sheath leaves at the base are about to fall off, the top is truncated and the germination is promoted. However, this method Using Hsinchu to propagate Hsinchu, due to the limited supply of nutrients in Hsinchu, the reproductive efficiency is limited; another statement: the bamboo stalk is 5-10cm away from the ground, cut a gap of 2 / 3 of the stalk diameter, and press it down, and bury the stalk to grow seedlings, but , because this method cannot move seedling materials, and the breeding site is limited by the environmental conditions around the mother bamboo, it is necessary to reserve a sufficient range of open space for burying seedlings in the nursery

However, the technical defect in this method is that the rooting hormone only acts on the outside of the branch, the action time is short, and it is easy to lose
