Abstract

The invention relates to a deinsectization method for rice seeds. The deinsectization method includes the steps of sun-curing, carbon dioxide treatment, cartap spraying, seal irradiation, screening and the like. The deinsectization method has remarkable deinsectization effect, wide deinsectization species, low cost and small side effects.

Description

A kind of deinsectization method of rice paddy seed

Technical field

The present invention relates to the agricultural planting field, relate in particular to a kind of deinsectization method of rice paddy seed.

Background technology

Paddy rice originates in Tropical Asian, after China widely plants, propagates into all over the world gradually.According to different point-scores, paddy rice can be divided into long-grained nonglutinous rice and japonica rice, early rice and middle late rice, glutinous rice and non-glutinous rice.The grain of rice that paddy rice is tied shell rear title rice or rice, nearly half population, all take rice as food in the world.The eating method of rice is varied, and rice, congee, rice cake, rice cake, rice noodles etc. are arranged.Paddy rice, except edible, can also be made wine, refine sugar and make industrial raw material, and rice husk, rice straw also have a lot of use.Therefore can say, paddy rice is people's basic staple food, and the plantation of paddy rice and results are also to weigh the major criterion of Agricultural Level.

For paddy rice, the quality of rice paddy seed will directly affect growth and the output of paddy rice.Yet, in storage, transportation and the arrangement process of rice paddy seed, insect pest but usually occurs.These insect pests have not only damaged the quality of rice paddy seed, even also may produce significant impact to the paddy rice product.In order to resist these insect pests, people often simply adopt the method for spraying medicine; But not only can not kill only according to spraying insecticide except kind insect widely, also may make these insects develop immunity to drugs, more may cause rice paddy seed itself to be subject to poisoning some side effects such as pollutions grade.

Therefore, be badly in need of the deinsectization method of the rice paddy seed that a kind of deinsectization effect is remarkable, the deinsectization kind is wide, with low cost, side effect is little.

Summary of the invention

Purpose of the present invention provides the deinsectization method of the rice paddy seed that a kind of deinsectization effect is remarkable, the deinsectization kind is wide, with low cost, side effect is little.

The technical solution used in the present invention is:

A kind of deinsectization method of rice paddy seed, comprise the steps:

(1) airing: rice paddy seed is placed under daylight and carries out airing, every 3 hours, rice paddy seed is carried out to a combing and stir, Exposure to Sunlight time every day is not less than 9 hours, and Exposure to Sunlight is 3 days continuously;

(2) carbon dioxide treatment: the rice paddy seed that will process through step (1) is placed in closed container, to injecting carbon dioxide in container, and makes the concentration of carbonic acid gas in container be not less than 85%, places 15 days;

(3) spray cartap: the rice paddy seed spray concentration that will process through step (2) is 60% cartap;

(4) sealing is irradiated: the rice paddy seed that will process through step (3) is placed in the clear glass seal box and carries out solar radiation, and irradiation time is not less than 10 hours;

(5) screening: the rice paddy seed that will process through step (4) is screened, choose have go mouldy, the rice paddy seed of pityriasis simplex, mildew, remaining puts into the warehouse cryopreservation.

Beneficial effect of the present invention is:

1, adopt the daylight airing, with low cost, be beneficial to operation, and insecticidal effect is remarkable;

2, adopted the carbonic acid gas of certain concentration to carry out deinsectization, not only for rice paddy seed, do not produced chemical residual, and ozone deinsectization cost is lower relatively, the deinsectization scope is more extensive;

3, adopt the cartap harmless to human body basic to carry out deinsectization to rice paddy seed, not only can not produce toxic and side effect, and with strong points, can effectively kill the rice insect pests such as the snout moth's larva of rice;

4, the solar radiation in sealed environment in step (4), not only can play dry moisture content, prevents the effect that insect pest is grown, and the environment of sealing also can avoid the subintrusion again of insect pest, guaranteed the deinsectization effect.
