Problems solved by technology

At the same time, due to the short suitable sowing time, the labor intensity of sowing is greatly increased.
[0003] In order to solve the contradiction between the benefits of timely and early sowing and the possible disadvantages of climate change, the sowing technology usually uses surface plastic film covering, but the use of surface plastic film covering will lead to poor ventilation and affect the aerobic respiration of seed germination At the same time, extensive use of plastic film is also the main cause of white pollution
Patent CN200910072511.3 discloses a preparation and method for physical rooting of rice seedlings in rice seedbeds. It uses oily or waxy long-chain substances as film substrates, sprays them evenly on the seed beds, and then sows them. This method improves the quality of the seeds. Oxygen conditions for seedling development, but also need excessive use, long-term use will bring many adverse effects on the land

Embodiment 1

[0015] Weigh 89.7% n-tetradecane (Fushun Shuanghong Wax Products Co., Ltd., melting point 5.5°C, n-alkane content 98%), 10% standard trihydric alcohol SGH320T (Shanghai Yizhu Industrial Co., Ltd.) and 0.3% metconazole (Future Reagent Company), mix and stir evenly at room temperature and set aside.

[0016] The corn seeds processed by the conventional method are placed flat in the sieve, and put into the above-mentioned pretreatment wax together at room temperature to ensure that all the corn seeds are immersed in the wax solution, take it out after shaking for a few times, and filter to remove the excess wax solution. Put the seeds in a refrigerated device at 0±1°C. After the wax liquid on the surface of the seeds solidifies into a dense protective film, put them in a paper outer packaging with an appropriate proportion of chemical fertilizers and store them in cold storage until sowing, and sow them according to the conventional method .

Embodiment 2

[0018] Weigh 85% n-tetradecane (Fushun Shuanghong Wax Products Co., Ltd., melting point 6.8 ° C, n-alkane content 98%), 13.2% diol SGH210N (Shanghai Yizhu Industrial Co., Ltd.) and 1.8% cyazofamid ( Future Reagent Company), mix and stir at room temperature until ready to use.

[0019] The corn seeds treated according to the conventional method are placed flat in the sieve, and put into the above-mentioned pretreatment wax together at room temperature to ensure that all the corn seeds are immersed in the wax liquid, shaken and taken out, after filtering to remove the excess wax liquid, put The seeds are placed in a refrigerated device at 0±1°C. After the wax liquid on the surface of the seeds solidifies into a dense protective film, they are placed in paper bags filled with appropriate proportions of chemical fertilizers and stored in cold storage until sowing, and sowed according to conventional methods.

Abstract

The invention discloses wax for plant seed pretreatment and a preparation method and an application method thereof. The wax consists of the following components in percentage by weight: 85-90% of hydrocarbon substances, 10-15% of humectant and 0.1-2% of bactericide. According to the wax disclosed by the invention, when the soil temperature is lower than the minimum temperature 8-10 DEG C required for plant seed germination, the wax substances form a dense solid protection film which effectively cuts off substance exchange between seeds and the outside to avoid bacterial infection, and the seeds can be protected from frost damage in the low-temperature soil in early spring while seed powder is avoided; when the soil temperature reaches the minimum temperature 8-10 DEG C required for plant seed germination, the wax substances are molten to form a liquid-state hydrophobic protection layer which is adhered to the surface of a plant seed and can inhibit the evaporation of moisture in the plant seed so that the seed contains proper moisture and the seed germination is promoted; after seed germination, the protection film formed by the wax substances is broken through, and the plant growth is not influenced.

Description

1. Technical field [0001] The invention belongs to the technical field of wax products, and in particular relates to a wax for pretreatment of plant seeds, a preparation method and a use method thereof. 2. Background technology [0002] Corn, soybean, sorghum, and millet are all annual grasses, which are important food crops and important feed sources. Timely sowing is an important measure to enable crops to obtain favorable climate conditions, full seedlings and strong seedlings, normal growth of plants, and timely maturity in each growth period from seed germination, emergence to maturity. The suitable sowing time of different crops is mainly determined by the characteristics of varieties, temperature, moisture, cultivation system, soil quality and topography. The growth period of the above-mentioned plants is short, and whether the sowing is appropriate or not directly affects the growth and yield of the crops. The temperature ranges required for germination of various ...
