Problems solved by technology

At the same time, yam is suitable for growing under the environmental conditions of mild climate, uniform rainfall, cloudy and foggy, and moderate sunlight. After overwintering, the yam tubers lose a lot of water, which is more than 30%. If the yam goes down for a long time without rain, the yam will delay or fail to emerge, which will seriously affect the yield of yam
However, the water retention of yam tubers is extremely difficult, and there is no simple and effective water retention treatment method.

Embodiment Construction

[0011] 1. Preparation of sterilized growth-promoting powder

[0012] The percentage by weight is 65% of high calcium powder, 25% of neem powder and 10% of potassium permanganate powder. First prepare high calcium powder according to the weight percentage of 15% of straw powder, 20% of flour and 65% of shell powder, stir evenly, crush through a 120 mesh sieve, and sterilize by microwave for use. The raw neem with insecticidal effect is dried and put into pulverizer to be broken, cross 120 mesh vibrating sieves. Potassium permanganate with bactericidal and sterilizing effects is put into a pulverizer and crushed, and passed through a 120-mesh vibrating sieve. The high-calcium powder, neem powder and potassium permanganate powder are evenly mixed according to the above weight percentage, which is the finished product of the sterilized growth-promoting powder.

Abstract

The invention provides an insecticidal sterilized water treatment method of Chinese yam species. The method comprises the steps of immersing Chinese yam tubers stored over the winter into tung oil for 5-7s and then fishing out, putting into the prepared sterilized promoting powder, fully warping the surfaces of the Chinese yam tubers by the sterilized promoting powder, and then seeding in the field. The Chinese yam tubers processed by the insecticidal sterilized water treatment method disclosed by the invention are early to germinate, and rapid to grow, not only can effectively prevent plant diseases and insect pests of the Chinese yam, but also can obviously improve the yield and the quality of the Chinese yam, and are low in pesticide residue after being continuously used, free of effect on the property of soil, and free of effect on the quality of the Chinese yam.

Description

[0001] technical field [0002] The invention relates to the technical field of yam tuber planting, and specifically provides a treatment method for insecticidal, sterilizing, and water-retaining yam seeds. Background technique [0003] Yam, also known as Dioscorea, Dioscoreaceae, is an annual or perennial twining vine with vines, often purple, cylindrical roots, opposite leaves, oval or oval, milky white flowers, and dioecious plants. Its underground expanded tubers are rich in starch, vitamins, protamine and mineral elements such as phosphorus, calcium, magnesium, iron, zinc, copper, potassium, etc. It has good taste, high yield and rich nutrition. It is a nutritious food suitable for all ages.
