Description
Technical field
The present invention relates to the yam cultivation technical field, specifically is the sterilization method of planting piece before a kind of Chinese yam cross-talk sowing.
Background technology
Chinese yam (Dioscorea opposita Thunb) belongs to Dioscoreaceae, is life in 1 year or perennial prehensile herbaceous plant.One of nutritive value, medical value and economic worth are high, grain, dish, medicine and raw material of industry dual-purpose, or the characteristic vegetable crop of China's foreign exchange earning.Its unit are economic flow rate and protein output are all high more than 1 times than cereal crops such as paddy rice, wheats.But prepared food is also raw-eaten, has the good health care effect.Chinese yam is regarded as little crop in the past, lacks system research always, causes that present kind is aging, culture technique is backward relatively, and industrialized development receives severely restricts.
At present China's Chinese yam modes of reproduction has bulbil (Chinese yam beans), Chinese yam young plant (Chinese yam mouthpiece) and 3 kinds of modess of reproduction of Chinese yam cross-talk (Chinese yam kind piece), wherein the Chinese yam cross-talk be that reproduction coefficient is higher, the subject mode of large-area applications in the production.That the Chinese yam cross-talk wants is highly efficient and productive, the high-quality cultivation, must chemicals treatment kind piece before the sowing and bask seeds.After with medicament is handled Chinese yam cross-talk two ends section, but both closed section prevented pathogen infection Chinese yam kind piece, can kill again and be enclosed in the inner pathogen of kind of piece, played the effect of diseases such as preventing and kill off rot and fusarium wilt.
Past people a kind of medicament commonly used such as white quicklime powder or powder of carbendazim are stained with and kind are disinfected, and also will be stained with prepared Chinese ink or red paint performs mark on the Chinese yam cross-talk with writing brush, sprout because have only the kryptoblast of upper end just can develop into bud.If not perform mark in advance or carefully recognize the direction of growth of root hair, just be difficult to confirm that which head is the upper end (near an end of terminal bud) of Chinese yam cross-talk, be easy to get wrong the upper and lower end direction of Chinese yam kind piece.If the direction misarrangement of Chinese yam cross-talk, cause the upper end of adjacent 2 kind pieces or lower end relative, the potato seedling after will causing the Chinese yam cross-talk to emerge is irregular, spacing in the rows is not of uniform size causes, and the relative person's spacing in the rows in upper end is less, and the relative person's spacing in the rows in lower end is bigger.
Summary of the invention
The present invention provides the sterilization method of planting piece before the sowing of a kind of Chinese yam cross-talk, makes the Chinese yam cross-talk two ends after the sterilization be easy to difference.
The present invention realizes with following technical scheme: the sterilization method of planting piece before a kind of Chinese yam cross-talk sowing; Sow preceding 25～30 days in the Chinese yam cross-talk intercepting of Chinese yam kind piece is become the Chinese yam cross-talk; Its two ends section application 2 kind has identical Disinfection Effect and shows that the medicament of different colours handles respectively; After the processing Chinese yam cross-talk is basked seeds, Chinese yam cross-talk two ends, the back section color of basking seeds is different, tells the upper and lower end of Chinese yam cross-talk according to two ends section color difference.
Described 2 kinds have identical Disinfection Effect and show that but the medicament of different colours is 70% mancozeb ultra micro wet-milling and quicklime powder.But the upper end section of Chinese yam cross-talk is stained with kind with 70% mancozeb ultra micro wet-milling, and the lower end section is stained with kind with quicklime powder.
Owing to adopted technique scheme; Treated Chinese yam cross-talk two ends section was both sterilized; Show different colours again; The result can tell the upper and lower end of Chinese yam cross-talk easily, and back potato seedling is neat evenly, the big or small unanimity of spacing in the rows thereby guarantee to emerge the Chinese yam cross-talk, reaches ideal cultivation target highly efficient and productive, high-quality.
The invention has the beneficial effects as follows: method is easy, is convenient to operation, and is effective.
