Abstract

The invention relates to a sugarcane reproduction technique by double buds of single stem of planting sparsely, which changes a conventional sowing method by multi buds of double stem to a sowing method by double buds of single stem of planting sparsely, with sowing quantity of 4000-5000 buds each Mu which is equal to cane stem of 0.4- 0.5 ton/Mu, the planting space of 90-110cm, the depth of 30-40cm, the width of furrow bottom of 20-30cm; the furrow bottom for flat cultivation of saplings by double buds of single stem is covered with fine soil by 2-5cm and then mulching films with 45cm width and 0.008cm thickness. By utilizing the effect of moisture and warming caused mulching films, early germination and emergence, tillering and growth and high emergence rate can be realized. In addition, the purposes of increasing number of cane plants per unit area and effective cane buds per plant and the multiple of reproduction of sugarcane saplings and promoting the growth of each plant can be achieved by fully utilizing biological characteristics of sugarcane tillering. Compared with conventional reproduction, the reproduction multiple is increased by over two times, saving buds of 5000-6000 per Mu, equal to saving cane stems of 500-600 kg per Mu.

Description

Bi-bud single file rare-seeding breeding method of sugarcane fine bread
Technical field
The present invention relates to a kind of bi-bud single file rare-seeding breeding method of sugarcane fine bread.
Background technology
Sugarcane is a kind of perennial perennial root crop that relies on sugarcane stem sugarcane bud breeding growth, and sugarcane field production planting every mu of needs then drops into seedling 10000 buds, amounts to 1 ton on sugarcane stem.At present, because the sugarcane land for growing field crops produces because of its sowing quantity is bigger, conventional breeding rate in existing land for growing field crops and efficient are low, the cost height, the breeding promotion rate of the new breeding of sugarcane is slow, introduces in sugarcane district to promote a new breeding of sugarcane and often need that the time could the popularization of formation scale for many years.
In the breeding of Sugarcane Superior Variety is promoted, at present, both at home and abroad the Sugarcane Superior Variety propagation technique that adopts mainly contain two kinds of tissue culture and the breedings of land for growing field crops conventional cultivation by way of.Though the former can carry out batch production production, realize the heavy fast of Sugarcane Superior Variety, but, because industrialized propagation production technology cost and tissue cultivating seedling field cultivation administrative skill require high factor restriction, Sugarcane Superior Variety industrialized tissue culture propagation technique still is difficult to promote towards sugarcane district peasant large-scale application.And the land for growing field crops conventional cultivation propagation technique of sugarcane district extensive use at present, because its traditional conventional cultivation administrative skill, the mode of sowing adopts the polygerm duplicate rows to connect the top and sows, the cane seedling sowing quantity is big, breeding rate and efficient are lower, planting every mu of needs then drops into about kind of bud 10000 buds, amounts to about 1.0 tons/mu of sugarcane stem.Collect seed the mashed root and stem of certain plants of back perennial root of following season, to lose the root and stem of certain plants serious, average every mu of effective sugarcane strain is only about 5000 strains during seed collecting, about 15 of the effective buds of average every strain, every mu of effective sugarcane bud 75000 buds of new breeding, breeding rate is 7.5 times of the amount of sowing, the breeding sowing quantity is big, and reproduction speed is slow, is difficult to satisfy the requirement that new breeding is promoted in sugar refinery fast.
Summary of the invention
The objective of the invention is to propose a kind of bi-bud single file rare-seeding breeding method of sugarcane fine bread, connect the top mode of sowing and be two bud single file light seedings mode of sowing by changing traditional polygerm duplicate rows, the every mu of amount of sowing 4000-5000 bud is amounted to sugarcane stem 0.4-0.5 ton/mu, plantation line-spacing 90-110cm, dark 30-40cm, ditch bottom width 20-30cm, the two bud single files of seedling are flat plants bottom of trench, covers 2-5cm with fine earth, use wide 45cm again, the plastic mulching of thick 0.008cm.The effect that heats by utilizing plastic mulching to preserve moisture, promote premature eruption to emerge, early tiller, early grow, improve and sprout emergence rate, make full use of the biological property propagation unit are sugarcane strain quantity that sugarcane tillers, promote the individual plant growth, reaching increases unit are sugarcane strain quantity and the effective sugarcane bud of individual plant quantity, improves the purpose of sugarcane kind bud breeding rate.
By season breeding, average every mu of effective sugarcane strain can reach about 6000 strains when sugarcane was collected seed, about 17 of the effective buds of every strain, and every mu of effective bud reaches 10.2 ten thousand buds, and effective sugarcane bud quantity reaches 20.4-25.5 times of the amount of sowing.Compare with the conventional breeding of tradition, breeding rate improves more than 2 times, saves kind of a bud 5000-6000 bud for every mu, is equivalent to every mu and saves sugarcane stem sowing quantity 500-600 kilogram.
The bi-bud single file rare-seeding breeding method of sugarcane fine bread that the present invention proposes, divide base manure and twice fertilising of topdressing the time of infertility in sugarcane production, base manure is sowed or perennial root is opened and carried out after the container made of bamboo, wicker, ratten, etc. is shone on the ridge in planting, use 80 kilograms/mu of composite fertilizers, impose when sugarcane production enters elongating stage, use urea 60-80 kilogram/mu.Other field management are identical with the management of land for growing field crops sugarcane conventional cultivation.
The bi-bud single file rare-seeding breeding method of sugarcane fine bread that the present invention proposes is a breeding rate height, saves with planting low cost, efficient height, the practical technique that operating technology is simple.
