Abstract

The cultivating method of zinc-enriched rice includes the following steps: before sowing in nursery bed, applying zinc vitriol in field, soaking rice seed in clear water for 1 day, then taking out, soaking the rice seed in 0.1% zinc-vitriol solution, and dressing said rice seed with 1-1.5% zinc oxide before pollulation of rice seed and coating, soaking root of young plant in 0.5-2% zinc vitrial solution, when the young plant has 2-5 leaves or in the stooling stage of young plant of field using 0.1-0.3 % zinc vitriol solution to spray it on foliage for 2-3 times, every interval is 7-10 days.

Description

The cultivation method of zinc-rich nutrient rice

The present invention relates to field of crop cultivation methods

Zinc is one of indispensable trace element of human body, and scarce zinc is a kind of worldwide deficiency disease.At present, the human body zinc supplementation generally is to add zinc element in food or in the medicine, and the zinc element of adding exists with inorganic zinc in food or medicine, and human body is difficult to absorb, and utilization rate of zinc is low, and by the medicine zinc supplementation, people have the sensation of taking medicine, and are out of favour.

Purpose of the present invention is exactly the deficiency that is difficult to absorption when adding zinc element to the human body zinc supplementation in food or medicine at above-mentioned, and a kind of cultivation method of zinc-rich nutrient rice is provided, and make and produce coming year rice and be rich in organic zinc, make people's zinc supplementation convenient, effective, the utilization rate of zinc height.

The present invention is achieved in that this method comprises the conventional rice cultivation method, and simultaneously, in the rice cropping process, by applying the zinc content that zinc element improves rice, its applying method is:

1), before seeding in nursery bed 1-3 days every mu spread fertilizer over the fields white vitriol 1-5 kilogram;

2), in the land for growing field crops every mu execute 2-4 kilogram white vitriol and make the rake leaven;

3), seed rice is put into clear water soak and to take out after 1 day, put into 0.05-0.2% white vitriol solution and soaked seed rice 24-48 hour;

4), the seed rice usefulness 1-1.5% zinc oxide seed dressing bag quilt before sprouting that will soak seed and get well;

5), use the white vitriol solution soaking rice shoot root of 0.5-2%;

6), when rice shoot 2-5 sheet leaf or land for growing field crops rice shoot tillering stage; The white vitriol aqueous solution with 0.1-0.3% sprays the blade face 2-3 time, each 7-10 days at interval;

7) tiller in the rice seedling bed when zinc deficiency symptom occurring early stage, every mu imposes zinc sulphate 1-1.5 kilogram.

The invention has the advantages that, by in the rice cropping process, applying the inorganic zinc element, anabolic action through paddy rice, the inorganic zinc that applies is changeed on behalf of organic zinc, be stored in the rice, organic zinc contained in this zinc-rich nutrient rice easily is absorbed by the body, as long as edible this zinc-rich nutrient rice, just can prevent and treat zinc dificiency effectively, under the soil zinc deficiency condition, paddy rice be applied zinc element simultaneously, can improve output effectively.

Embodiment: the cultivation method of zinc-rich nutrient rice, except comprising the conventional rice cultivation method, can in the rice cropping process, use zinc element dribs and drabs, concrete grammar is: 1) spread fertilizer over the fields 2 kilograms of white vitriols for every mu preceding 2 days of seeding in nursery bed;

2) in the land for growing field crops every mu execute 3 kilograms of white vitriols and make the rake leavens;

3) seed rice is put into clear water and soaked taking-up after 1 day, put into 0.1% white vitriol solution and soaked seed rice 30 hours;

4) the seed rice usefulness 1-1.5% zinc oxide seed dressing bag quilt before sprouting that will soak seed and get well;

5) with 1% white vitriol solution soaking shoot root portion 1 minute;

6) when rice shoot 2-5 sheet leaf or land for growing field crops rice shoot tillering stage; The white vitriol aqueous solution with 0.1-0.3% sprays the blade face 2 times, each 7 days at interval;

7) tiller in the rice seedling bed when zinc deficiency symptom occurring early stage, every mu imposes 10 kilograms in zinc sulphate.

" Jingmen Hong Sen limited industrial company " passes through " Ministry of Agriculture's food quality supervision inspection " center " check; its zinc content reaches per kilogram 20.5 grams; reach the standard of GB14880-94, i.e. " State Standard of the People's Republic of China's food enrichment uses sanitary standard " by the zinc-rich nutrient rice of producing with this method (big vast gloomy scented rice).

Claims (1)

1, the cultivation method of zinc-rich nutrient rice comprises the conventional rice cultivation method, it is characterized in that: in the rice cropping process, by applying the zinc content that zinc element improves rice, its applying method is:

2), in the land for growing field crops every mu execute 2-4 kilogram white vitriol and make the rake leaven;

3), seed rice is put into clear water soak and to take out after 1 day, put into 0.05-0.2% white vitriol solution and soaked seed rice 24-48 hour;

4), the seed rice usefulness 1-1.5% zinc oxide seed dressing bag quilt before sprouting that will soak seed and get well;

5), use the white vitriol solution soaking rice shoot root of 0.5-2%;

6), when rice shoot 2-5 sheet leaf or land for growing field crops rice shoot tillering stage; The white vitriol aqueous solution with 0.1-0.3% sprays the blade face 2-3 time, each 7-10 days at interval;

7), the early stage of tillering in the rice seedling bed, every mu imposed zinc sulphate 1-1.5 kilogram when zinc deficiency symptom occurring.
