Abstract
The soybean seed preparing and preserving method includes picking fresh bean pod to collect seed, drying seed in shady and cool condition, coating seed with soybean coating agent of 25 % concentration and comprising chitin, bacillus thringiensis, natto resin, trace element, guar gum, etc. capable of affecting physiological metabolism, and storing at low temperature condition. The said method can keep soybean seed from the high temperature and rainy condition, prevent and control diseases and pests and raise germination rate.
Description
Technical field
The present invention relates to a kind of production of hybrid seeds store method of spring-sown type, relate in particular to a kind of production of hybrid seeds store method of subtropical zone, belong to plant genetics and breeding and production of hybrid seeds manufacture field.
Background technology
The subtropical zone spring-sown type is that a kind of dish of eating usefulness raw is used soybean, and in the sowing in following April of no facility outdoor cropping condition, gather in the crops late June to August in the production, and results back seed is stored in 1 year spring.Because subtropical zone 6-8 month high temperature and rainy, make the very fast sex change of soybean protein cause seed to lose vitality, thereby be that green soy bean breeding or the soybean varieties suitable of producing are bred the germination (Wu Siming (1956) Zhejiang agricultural college journal, Wang Jinling (1970) " soybean ") that all can't guarantee seed.This spring-sown type is in weather conditions and summer that the harvest season ran into, the autumn soybean and the weather conditions of Spring Sowing Soybean in Northern significantly different.The subtropical zone gathers in the crops after producing and going up the spring-sown type physical maturity at present, and losing vitality can't reserve seed for planting, and it is extremely low to gather in the crops percentage of seedgermination in the scientific research after the physical maturity.The subtropical zone spring-sown type production of hybrid seeds is the difficult point that hinders soybean breeder and production.How preserving the spring-sown type seed of subtropical zone, improve percentage of seedgermination and effectively prevent after planting damage by disease and insect, is an important research project.Existing store method to the common soybeans seed has the outer covering of the seed of employing packaging technique to handle, wherein the agent of " middle dragon " board good fortune more than 30% gram soybean kind clothing is China Agricultural University's latest scientific research, its kind clothing agent Main Ingredients and Appearance is a chemical substance, comprise carbofuran, tmtd, carbendazim, active ingredients such as trace element, concrete prescription is: carbofuran % 〉=12.0, tmtd % 〉=11.0, carbendazim % 〉=7.0.The agent of this gram of good fortune more than 30% soybean kind clothing is primarily aimed at common soybeans and prepares, and not exclusively adapts to the characteristics that the subtropical zone comprises the spring soybean of areas to the south, the Changjiang river, needs the new technical solution of research.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, the production of hybrid seeds store method of a kind of subtropical zone spring-sown type is provided, be easy to implement, can effectively solve the seed sex change and lose blodynamic problem, improve percentage of seedgermination.
For realizing such purpose, in the technical scheme of the present invention, the bar of adopt the living bright pod production of hybrid seeds of gathering in advance, at the threshing precipitation of under the shady and cool condition seed packing spreading for cooling being dried after shady the doing, the soybean of adopting by efficient safety such as chitin, bacillus thuringiensis,Bt, natto resin, trace element, guar gum then and having the formulated active ingredient 25% of the biologic product that influence physiological metabolism protects the bud seed coating medicine, with the storage down of cryogenic conditions behind the special dressing of dry seeds.Make the pod of soybean maturation and the natural conditions that seed is avoided high temperature and rainy, have the effect that prevents insect and keep the high germination rate.
The inventive method comprises following concrete steps:
1, bar alive is in advance plucked bright pod.Break the conventional method that soybean was gathered in the crops in the ripe full ripening stage of ringing a bell, the drum grain intermediary and later stages before soybean pod, bar yellowing, the bar of living is in advance plucked fresh green-pod soybean as seed.
2, the packing spreading for cooling is avoided tanning by the sun.Seed is divided into pouch, general 1kg/ bag or thin layer 5-10cm, spreading for cooling under shading condition is avoided tanning by the sun and rainwater.
3, blowing threshing precipitation is shady does.Adopt cool breeze below 30 ℃ that seed is shady dried, the threshing then in 5-7 days of drying also can be dried behind the early threshing.Wind speed 3-5 meter per second makes the soybean water content reduce to 11-13%.
4, seed pelleting low-temperature storage.Adopting percentage by weight is the chitin of 0.9-1.1%, 7.0% bacillus thuringiensis,Bt, 15.0% natto resin, the trace element of 0.4-0.6%, the guar gum of 1.4-1.6% and auxiliary material are mixed with 25% soybean guarantor bud seed coating medicine, adopt seed pelleting machine at the outer covering of the seed dressing, and seed is 1: 50～100 with the ratio of seed coating medicine, regulate PH6.0～7.0, in 4-10 degree environment, preserve behind the seed pelleting.
In the coating agent for seed that the present invention adopts; chitin can adopt that molecular weight is 5000, deacetylation degree 91, water miscible chitin; bacillus thuringiensis,Bt is a wettable; molecular weight 13000, natto resin employing purity is 80% pulvis, trace element comprises molybdenum; phosphorus; potassium pulvis chemical pure, guar gum are 100% pulvis, and auxiliary material employing corn flour and dyestuff pearl are red.Add an amount of chitin and help improving the sterilization and the soya seeds physiological metabolism effect of protecting the bud seed coating medicine, add the effect that kills off the insect pests that an amount of bacillus thuringiensis,Bt helps protecting the bud seed coating medicine, add an amount of natto resin and help sterilization and promote growth of seedling, add the effect that an amount of guar gum helps reducing soybean breathing and physiological metabolism.
The present invention is according to the characteristics of subtropical zone spring soybean reproductive growth, break the conventional method that soybean was gathered in the crops in the ripe full ripening stage of ringing a bell, in the drum grain middle and later periods of soybean, the bar of living is in advance plucked fresh green-pod soybean, after the spreading for cooling threshing is handled, adopt the seed pelleting low-temperature storage, the capsuled seed breakage rate is less than 0.1-0.3%, generally in 4-10 degree temperature adjustment warehouse, be saved to late October taking-up sowing, also can be saved in the 4-5 month in 1 year always, keep germination rate at 92-96%, and have and well prevent the insect effect.The invention solves areas to the south, the Changjiang river spring soybean under high temperature, high humidity environment condition, lose percentage of seedgermination and pest damage problem, changed the method for the necessary northern production of hybrid seeds of areas to the south, the Changjiang river spring soybean, significant to southern spring soybean plantation.
