Abstract
The invention discloses high-moisture seed protecting method, the method comprises: the force ventilation of high-moisture seed is stored up step temporarily; By baked seed to the step of safe storage standard moisture; By the step of described roasted seed warehouse-in safe storage.The invention solves high-moisture seed harvest to the preservation problem of drying during this period of time, can seed vitality be ensured, again for effective time is won in drying work.The seed acquisition of having guaranteed both quality and quantity of seed produces enterprise is even more important, and the present invention alleviates in the short time and gets the harvest in quickly and conservation contradiction; Also do not affect by enterprise's drying capacity deficiency; And strain under raising adverse weather condition, anti-disaster ability, realize many conservations, protect the target of good kind.
Description
Technical field
The present invention relates to seed conservation manufacture field, be specifically related to purchase high-moisture wheat, rice paddy seed protecting method.
Background technology
The protecting method traditional method of wheat, rice paddy seed is, after the harvesting of field, carry out the airing in time of one-phase ground, oven dry, then put safe storage in storage, general wheat seeds GB safe storage moisture is 13.0%, and rice seed GB safe storage moisture is 14.5%.Climate and the impact of Seed enterprises drying capacity, do not reach the seed of safe storage moisture as dealt with improperly, and seed quality index will be difficult to ensure.And along with progressively improving in agricultural workforce's minimizing and mechanization degree ground, high-moisture seed directly pays the ground an urgent demand of selling purchase enterprises and more and more becoming base peasant household after the harvesting of field.
Crop seeds is a lived organism, if its moisture does not reach the standard moisture of seed safety storage, add the afterripening of seed own, the respiratory intensity of seed is large, and the amount of oxygen of needs is also relatively many, high-moisture seed is once upper heap or warehouse-in, the oxygen consumed is mainly derived from the oxygen in seed heap internal clearance, and when oxygen is not enough, seed is forced into anaerobic respiration, produces lactic acid and alcohol in body, can embryo be poisoned after accumulation, make embryo poisoning until dead.So how to adapt to the situation, after carrying out results, high-moisture is to the conservation work during this period of time of standard moisture, is the technical bottleneck of current Seed enterprises conservation.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of high-moisture seed protecting method is provided, solve high-moisture seed from results to drying rear warehouse-in preservation problem during this period of time, ensure the vigor of seed, for baking operation wins effective time, alleviate Seed enterprises and get the harvest in quickly the contradiction with conservation, weaken the impact of weather on conservation simultaneously.
The present invention is achieved through the following technical solutions:
High-moisture seed protecting method, the method comprises:
The force ventilation of high-moisture seed is stored up step temporarily,
Described force ventilation is stored up temporarily to adopt and in warehouse, is arranged ventilating duct to close a position stackings, and blower fan is communicated with ventilating duct and ventilates, or arranges ventilating duct in grain bin, and store up external and stack with moulding cloth sealing, blower fan is communicated with ventilating duct ventilation; Described ventilating duct is the pipeline communicated that interweaves in length and breadth be located at warehouse or stored up bottom, and pipeline is densely covered with air-vent;
By baked seed to the step of safe storage standard moisture;
By the step of described roasted seed warehouse-in safe storage;
The further improvement project of the present invention is, described force ventilation is stored up temporarily in step and required that in grain layer, air-flow blind area unanimously, does not appear in uniform stream, and grain temperature control is no more than natural temperature.
The present invention further improvement project is, described high-moisture seed separately stores up temporarily by kind, moisture difference, the seed grain moisture scope difference 0 ~ 3% of storing up temporarily with storehouse.
The present invention further improvement project is, the time that step is stored up in described force ventilation is temporarily no more than 20 days.
The present invention further improvement project is, described warehouse grain layer height controls below 4 meters, and the distance between the parallel ventilated road in warehouse is less than grain layer height; Described grain bin diameter is within 7 meters, and cylinder height is below 4 meters, and upper cone height is below 3 meters.
The present invention further improvement project is, described force ventilation is to ventilating duct air blast or air draught by blower fan.
The present invention further improvement project is, described blower fan adopts T4-72 type centrifugal fan, more than blast 1400pa.
The present invention compared with prior art, has following obvious advantage:
One, the high-moisture seed respiration after results is very vigorous, and after seed purchase warehouse-in is hoarded, because not carrying out drying and processing in time, easily cause embryo poisoning even dead, seed becomes bud rate Quality Down.Before the present invention includes baking step, the force ventilation of high-moisture seed is stored up step temporarily, solve high-moisture seed harvest to the preservation problem of drying during this period of time, can seed vitality be ensured, again for effective time is won in drying work.The seed acquisition of having guaranteed both quality and quantity of seed produces enterprise is even more important, and the present invention alleviates in the short time and gets the harvest in quickly and conservation contradiction; Also do not affect by enterprise's drying capacity deficiency; And under raising adverse weather condition strain, anti-disaster ability, realize many conservations, protect and plant target.
Two, store up process temporarily by force ventilation, accelerate the afterripening of blue or green seed, the moisture between each batch of different in moisture seed grain simultaneously balancing Seed enterprises purchase, and reduce the effects such as grain temperature, be convenient to next step seed grain oven dry operation.
Three, cost of the present invention is low, easy and simple to handle, is easy to promote.
Four, enforcement of the present invention, accelerates field production harvesting progress, rises stubble in time, and lower season crop is obtained initiatively, has complied with plantation family and has been reluctant airing, directly paid requirement and the hope of Seed enterprises after the harvesting of field.
