Abstract
The invention discloses a double-bud oblique sowing breeding method for healthy sugarcane seed stems. The method comprises the following steps of: selecting primary seed stems or secondary seed stems of healthy sugarcane seedlings serving as a seed source; growing the primary seed stems or the secondary seed stems of the healthy sugarcane seedlings for 6 to 8 months in a field; and cutting the primary seed stems or the secondary seed stems of the healthy sugarcane seedlings into double-bud stem sections, obliquely putting the double-bud stem sections at the bottom of a planting ditch, wherein the stem sections and the planting ditch form included angles of 40 to 50 degrees, the distance between the stem sections is 45 to 55 centimeters, and the seed consumption of each mu is averagely 2,200 to 2,700 buds. By adopting the method, the seed consumption of the sugarcane is greatly reduced, the sugarcane buds are distributed uniformly, natural conditions are fully utilized, the tillering and stem forming rate of the healthy seed stems is improved, and high yield is achieved.
Description
Technical field
The present invention relates to the two buds of a kind of sugarcane health kind stem and tiltedly broadcast propagation method.
Background technology
A kind of perennial perennial root crop of sugarcane owing to carry out vegetative propagation with trophosome kind stem for a long time, unavoidably can cause mosaic disease, ratoon stunting disease, the accumulation of smut pathogene in seedling, thereby causes deterioration of variety, the underproduction and sugar to descend.Application of health seedling technology is to recover the measure of sugarcane good strains of seeds best techniques at present.This technology detoxification efficiency is good, can slough sugarcane viruses such as mosaic of sugarcane, ratoon stunting disease, and reduces the harm of fungal diseases such as smut, helps the purification and rejuvenation of kind, and obvious effect of increasing production, amount of increase in production can reach more than 15%, and high reaches 50%; Realize factorial seedling growth, varietal purity is high, and breeding rate is big, helps industrialization and the promotion rate of accelerating new varieties.But still by present conventional cultivation method, its every mu of amount of sowing is at 8000-10000 bud in secondary, three grades of kind stem breeding technology for health seedling.Because the new plant cane sowing quantity is big, it is low to breed coefficient, and cost is high, also can't give full play to healthyly to plant stem many advantages of tillering, thereby restrict applying of the long-pending seedling technology of sugarcane health.One Chinese patent application 200610011017.2 has announced that the wide capable double-bud horizontally of a kind of sugarcane plants the full-film mulching and planting method, change traditional rectangular cultivation of placing vertically into traverse short section cultivation, but the amount of sowing is close with conventional method; One Chinese patent application 200710066472.7 has been announced a kind of bi-bud single file rare-seeding breeding method of sugarcane fine bread, traditional polygerm duplicate rows is connect the top mode of sowing change two bud single file light seedings mode of sowing into, but its amount of sowing is still on the high side.
Summary of the invention
The purpose of this invention is to provide the two buds of a kind of sugarcane health kind stem and tiltedly broadcast propagation method, the sugarcane sowing quantity is reduced significantly, the sugarcane bud is evenly distributed, and makes full use of natural conditions, improves the healthy stem of planting and tillers into the stem rate, thereby reach higher yield.
The present invention achieves the above object through following technical scheme: the two buds of a kind of sugarcane health kind stem are tiltedly broadcast propagation method, comprise the steps:
(1) provenance is the one-level kind stem or the secondary kind stem of sugarcane health seedling;
(2) the one-level kind stem of sugarcane health seedling or secondary kind stem are 6-8 month in the grown in field time;
(3) one-level kind stem or the secondary kind stem with said sugarcane health seedling is chopped to two leaf stem sections; Tiltedly be placed on the plantation bottom of trench to said pair of leaf stem section; The stem section becomes 40 °～50 ° with the plantation ditch, and distance is 45～55cm between stem section and the stem section, and the average every mu of amount of sowing is 2200～2700 buds.
Described sugarcane health seedling is meant the sugarcane tissue-culture nutrient cup seedling that does not contain any pathogeny bacterium or plants stem.
Said one-level kind stem is the cane stalk that sugarcane health group training nutrient cup seedling grows up to behind field planting.
Said secondary kind stem is the cane stalk that grows up to behind the one-level kind stem plantation land for growing field crops.
The technique effect that the present invention gives prominence to is:
The sugarcane of the present invention plantation, through growth in 6～8 months, each was planted bud and can grow 4～6 strain sugarcanes are arranged, and 18 of average every strain sugarcanes are more than the bud, and average every mu of effective bud number can reach more than 17.6 ten thousand.Compare with traditional approach, breed coefficient and improve more than 4 times.
The practical implementation method
Below through specific embodiment technical scheme of the present invention is further described.
Embodiment 1
The two buds of a kind of sugarcane health kind stem are tiltedly broadcast propagation method, comprise the steps:
