Abstract

The invention provides a breeding method for organic rice. The method comprises the following steps: 1) seed preparation; 2) seed pretreatment; (3) bed soil preparation; 4) bed preparation and seeding; 5) seedbed management; and 6) seedling pulling. A rice seedling cultivated by using the method in the invention has a seedling stage prolonged by 7 days, a seedling age improved by 1.3 leaves and a seedling-bed tiller number increased by 0.6 tiller, so a big seedling with the seedling age of more than 44 days, a leaf age of more than 5 leaves and an average tiller number of more than 1.3 tillers in the seedling stage is bred; and a germination accelerator used in the invention can improve budding rate of rice seeds.

Description

A kind of breeding method of organic rice

Technical field

The present invention relates to a kind of breeding method of organic rice.

Background technology

Paddy rice originates in Tropical Asian, after China widely plants, propagates into gradually all over the world.According to diverse ways, 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 research of China scientist Yuan Longping to hybrid rice makes a great contribution, and is described as " father of hybrid rice ".Paddy rice institute knot reality and paddy, claim rice, scented rice, rice after paddy (grain) shells.Nearly half population is in the world all food with rice.The eating method of rice is varied, has rice, congee, rice cake, rice cake, rice wine etc.Paddy rice, except edible, can also be made wine, refine sugar and make the raw material of industry, rice husk, rice straw, can as feed.Mainly the Northeast, the Yangtze river basin, China paddy rice main producing region, Pearl River Delta.Belong to direct economy crop.Still the staple food of 1/3rd mankind in the world.

Organic paddy rice refers to the material such as agricultural chemicals, chemical fertilizer, growth regulator not using chemosynthesis, and follows the course of nature and Ecological Principle, adopts the agrotechnique of a series of sustainable development, maintains the paddy rice of continual and steady agriculture process of growth plantation.

Summary of the invention

The invention provides a kind of breeding method of organic rice.

The invention provides a kind of breeding method of organic rice, step is as follows:

1) seed is prepared;

2) Seeds preprocess: by after the seed airing chosen, the salt solution putting into proportion 1.14 salt solution stirs simultaneously, discards the rice seed floated, and the rice seed clear water sunk cleans salt; Put into germinator afterwards and soak 2-3 days; The preparation method of described germinator is: pulverize after Radix picrorrhizae 15-20 weight portion, Radix Astragali 8-10 weight portion, rhizoma zingiberis 20-25 weight portion, the mixing of root of kudzu vine 3-5 weight portion, the water adding 200 weight portions is heated to 100 DEG C and extracts 3 times, each 2 hours, merge also concentrated filtrate and, to the half of filtrate original volume, obtain medicament concentrate; By medicament concentrate dilution 20-25 doubly, germinator is obtained;

3) bed soil prepares: after selecting the soil without grass-seed and germ to sieve, as native without fertile bed;

4) bed and sowing is done;

5) seedbed management:

Between the seeding stage, ensure that moisture is sufficient, canopy membrane closure is incubated; Rice paddy seed be unearthed more than 80% time fine day open canopy film carry out one day shine seedling; Water 1 water every day; After emerging, day temperature controls at 25-30 DEG C, and nocturnal temperature controls be not less than 5 DEG C, and waters foliage fertilizer once every spray in 3-4 days; Described in every 1L, the preparation method of foliage fertilizer is as follows: be dissolved in deionized water by urea 0.12-0.18g, dipotassium hydrogen phosphate 0.07-0.09g, ammonium molybdate 0.02-0.04g, Firebrake ZB 0.03-0.05g, sodium nitrate 0.006-0.008g, ferrous sulfate 0.002-0.004g, magnesium sulfate 0.002-0.004g, manganese sulphate 0.002-0.003g, copper sulphate 0.006-0.008g, sodium citrate 0.005-0.008g, be settled to 1L;

6) pull up seedlings.

The rice seedling cultivated by the present invention extends 7 days seedling stages, improves seedling age 1.3 leaf, increases rice seedling bed and tillers 0.6, bring out seedling age more than 44 days, more than leaf age 5 leaf, seedling stage the mean tillering more than 1.3 seedlings; Germinator used in the present invention can improve the bud ratio of rice paddy seed.
