Embodiment

[0024] A cold resistant agent for rice, which is formed by mixing and stirring the following raw materials in parts by weight:

[0025] Allantoin 22

[0026] Proline 15

[0027] Glycine 15

[0028] Potassium dihydrogen phosphate 15

[0029] Boric acid 12

[0030] Zinc sulfate 12

[0031] Manganese Sulfate 8.

[0032] Soak early rice seeds with 1000 times solution of this anti-cold agent for 20-36 hours, and spray with 1000 times solution of this product once at the stage of one leaf and one heart and two stages of two leaves and one heart, which can significantly enhance the cold resistance of seedlings and prevent rot The seedling effect is very obvious. The field test proves that the rate of seedling growth is 8.5-10 percentage points higher than that of the blank control of open-field seedlings and 5-10 percentage points higher than that of the blank control of plastic-filmed seedlings by using this product to treat early rice seeds and seedlings; The blank control i...

Abstract

The invention discloses a cold-resistant agent for rice. The cold-resistant agent is formed by mixing and uniformly stirring the following raw materials in parts by weight: 20-25 of allantoin, 10-20 of proline, 10-20 of glycine, 10-20 of potassium dihydrogen phosphate, 10-15 of boric acid, 10-15 of zinc sulfate and 5-10 of manganese sulfate. After the raw materials are scientifically combined, the effect is composited; and field trials prove that after the rice is sprayed by 1000 times of solution of the product, the bound water and the chlorophyll of plants can be improved, the permeability of cell membranes is reduced, the cold tolerance of rice seedlings and plants is obviously improved, the damage of cold dew wind is effectively avoided, the ripening rate and the thousand seed weight are improved, the ageing of functional leaves and branches of rice can be delayed, and the lodging-resistance effect is obvious.

Description

technical field [0001] The invention relates to chemical products, in particular to a cold-resistant agent for rice. Background technique [0002] Rice is a short-day crop that likes temperature and humidity. The heat resource is generally ≥10°C. Places with an accumulated temperature of 2000-4500°C are suitable for planting one-crop rice, places with 4500-7000°C are suitable for planting two-crop rice, and places with 5300°C are suitable for double-crop rice. Safety limits, three-season rice can be planted in places above 7000 °C. In areas where double-cropping rice is planted, early rice should be sown earlier in spring in order to catch up with the season, but it will cause "rotten seedlings" when it encounters "cold spring" weather; cause rice yield reduction or loss. [0003] At present, in order to prevent the impact of "cold spring" on the seedlings, plastic film is generally used, but it is labor-intensive and time-consuming, and increases production costs. To pre...
