Embodiment 1

[0020] First take 1.00 g of glucose, 0.15 g of polyethylene glycol, 1.50 g of choline chloride, 0.40 g of calcium chloride, and 96.95 g of distilled water, and mix 1.00 g of glucose, 0.15 g of polyethylene glycol, 1.50 g of choline chloride, Dissolve calcium chloride in 10 grams of distilled water respectively, mix several medicines, then add the remaining distilled water, mix well, and let stand at room temperature for 0.5 hour to obtain the preparation. Applying the preparation of the present invention to Xianyu 335 corn achieves good results. On June 12, 2008, the seeds were soaked in warm water for 16 hours and then transferred to a petri dish lined with moist filter paper, and germinated in an artificial climate box at 25°C to keep the seeds fully moist. When the seedlings grow to 2 leaves and 1 heart, the preparation of the present invention is sprayed, and the control is treated with clear water, and the next day, 5°C low temperature stress treatment is carried out. Th...

Embodiment 2

[0022] First take 0.5 g of glucose, 0.05 g of polyethylene glycol, 2.50 g of choline chloride, 0.30 g of calcium chloride, and 96.60 g of distilled water, then mix 0.5 g of glucose, 0.05 g of polyethylene glycol, 2.50 g of choline chloride, 0.30 g Dissolve calcium chloride in 10 grams of distilled water respectively, mix several medicines, then add the remaining distilled water, mix well, and let stand at room temperature for 0.5 hour to obtain the preparation. The preparation of the present invention is applied to Dafeng No. 26 corn. On June 20, 2008, the seeds were soaked in warm water for 16 hours and then transferred to a petri dish lined with moist filter paper, and germinated in an artificial climate box at 25°C to keep the seeds fully moist. When the seedling grows to 2 leaves and 1 heart, the preparation of the present invention is sprayed, and the contrast is treated with clear water, and the next day, 5°C of low temperature stress is carried out, and the temperature ...

Embodiment 3

[0024] First take 2.00 grams of glucose, 0.10 grams of polyethylene glycol, 3.00 grams of choline chloride, 0.20 grams of calcium chloride, 94.70 grams of distilled water, and mix 2.00 grams of glucose, 0.10 grams of polyethylene glycol, 3.00 grams of choline chloride, 0.20 grams Dissolve calcium chloride in 10 grams of distilled water respectively, mix several medicines, then add the remaining distilled water, mix well, and let stand at room temperature for 0.5 hour to obtain the preparation. The preparation of the present invention is applied to Zhengdan 958 and Jinyu 811 corns, and has good anti-low temperature effect. It was sown in the field on April 20, 2009 (the temperature from May 1 to 10, 2009 was lower than normal). Seedlings emerged on April 28, sprayed with calcium preparations at the stage of 1 leaf and 1 heart, and treated with water as the control, 30 plants per treatment, repeated 3 times, and the area of ​​the plot was 10.05m 2 15 days later, the fresh and d...

Abstract

The invention discloses a low-temperature-resistance growth substance applied to corns and a preparation method thereof. The preparation is prepared from the following ingredients in percentage by weight: 0.05 part to 2.00 parts of glucose, 0.05 part to 0.15 part of polyethyleneglycol (PEG400), 1.50 parts to 3.00 parts of choline chloride, 0.20 part to 0.40 part of calcium chloride and 94.45 parts to 97.75 parts of distilled water. The preparation method comprises the following steps: firstly, respectively dissolving 0.05 part to 2.00 parts of glucose, 0.05 part to 0.15 part of polyethyleneglycol (PEG400), 1.50 parts to 3.00 parts of choline chloride, and 0.20 part to 0.40 part of calcium chloride into 10 parts of distilled water; uniformly mixing several kinds of medicine; then, adding the rest distilled water; uniformly mixing the materials; and obtaining the preparation after still standing for 0.5 hour at the normal temperature. The low-temperature-resistance growth substance of the invention has the advantages of obvious low-temperature-resistance effect, convenient use and low cost. When being used during the coming of the low temperature in the corn seedling period, the low-temperature-resistance growth substance can obtain good low-temperature-resistance effect, and the loss caused by temporary temperature reduction can be greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting management, and particularly relates to a low-temperature anti-growth growth agent applied to corn and a preparation method thereof. Background technique [0002] Corn is one of the main food crops in my country. Due to late frost and late spring cold, the seedlings often suffer from low temperature, which seriously affects the growth and development of corn, and even causes a large reduction in production. In recent years, due to the increase in the frequency of extreme climate changes, uneven cold and heat, and frequent low-temperature disasters, the frequency of low-temperature disasters for corn has also increased, which has become one of the key limiting factors for high-efficiency and high-quality production of corn. At present, the measures taken to prevent low temperature in corn production include: (1) adopt new low temperature resistant varieties; Use foliar spraying growt...
