Pinellia ternate soilless float breeding method

Abstract

The invention belongs to the technical field of crop seedling production, and discloses a pinellia ternate soilless float breeding method. Pinellia ternate seed selection, bulb disinfection, float breeding, seedling stage management, growth time management, seedling hardening and transplanting are carried out to complete pinellia ternate float breeding. The problems that an existing pinellia ternate breeding method cannot be separated from the bondage of soil and adverse factors of external natural conditions, diseases and insect pests of pinellia ternate are easily caused due to the hazards of soil-borne diseases, insects and weeds, the root system is underdeveloped, the uniformity is low, the stress resistance is poor, the transplanting and seedling returning are slow, the survival rateis low, and the economic benefit is not obvious are solved. According to the pinellia ternate soilless float breeding method, 0.1% of potassium permanganate is used for disinfection, the defects of previous disinfection with carbendazim, chlorothalonil or other chemical agents are overcome. Chemical agent disinfection, on the one hand, brings pesticide residues and may also have certain influenceon pinellia ternate germination. However, the potassium permanganate, as a strong oxidant, has no influence on crop germination at low concentration and does not have any influence on pinellia ternatequality.

Description

technical field [0001] The invention belongs to the technical field of crop seedling production, and in particular relates to a soilless floating seedling raising method for Pinellia pinellia. Background technique [0002] Currently, the closest prior art: [0003] Pinellia is the tuber of Pinellia temate (Thunb.) Breit., a plant of the genus Pinellia in the family Araceae. It has the functions of drying dampness and resolving phlegm, reducing adverse reactions and relieving vomiting, and has the effect of reducing boils and swelling when used raw. It is a traditional Chinese medicinal material commonly used in my country. With the development of traditional Chinese medicine, the market demand for pinellia has been increasing in recent years, and the price has also been rising. Planting pinellia has become an important new way to get rich in its authentic production areas. With the increase of Pinellia's medicinal and export demand, its wild resources are difficult to meet ...

AI Technical Summary

Problems solved by technology

[0007] (1) However, the traditional seedling raising technology is greatly affected by the climate and environment, and is easily affected by diseases and insect pests. Especially once the stem rot and soft rot break out, the seedlings will face failure, which is very unfavorable for the large-scale and sustainable greening of the pinellia industry develop

[0008] (2) The existing Pinellia seedling raising method cannot break away from the shackles of the soil and the adverse factors of external natural conditions. Because of the harm of diseases, insects and weeds carried by the soil, it is very easy to cause diseases and insect pests in Pinellia, and the root system is underdeveloped and neat. Low degree of stress, poor stress resistance, slow transplanting and return to seedlings, low survival rate, and inconspicuous economic benefits

[0009] (3) The existing technology is easy to cause dry holes. Most of the predecessors used plastic foam floating plates as floating plates, which do not absorb water and do not retain water. The matrix is ​​too loosely filled, causing the matrix to leak from the bottom hole of the floating plate when the floating plate is placed in the floating pool, and the matrix in the hole forms a fault, causing the water to not absorb moisture to the surface normally, thus affecting the emergence of seedlings

[0010] (3) The existing seedling raising technology is mainly carried out in the field, relying on greenhouse facilities, the operability per unit area is poor, space expansion cannot be realized, and the seedling breeding coefficient is low

[0011] (4) The prior art involves complex formulations of various culture media, which is not conducive to ordinary people's mastery, and the operation is difficult. (5) The prior art is prone to chilling injury

[0012] (6) Existing technology is prone to heat damage

[0013] (7) Existing technologies are prone to salt damage

[0015] (1) In Pinellia producing areas, no one has considered the method of floating seedlings at present, and most of them still use the direct seeding method to raise seedlings, and the harvest depends on the weather
