In Yunnan, Mid-Levels summer cabbage disease prevention Cultivation Techniques
A period of great importance, we must note the following technical problems. 1 heel heel construction shed shed built in the ground generally flat, lee, good drainage, place a full light, in order to avoid re-infection, virus-free tissue culture virus, required within a radius of around 500m free banana groves. Land use with 0.1% before spraying the soil potassium permanganate solution for disinfection. In a typical hot and humid climate, autumn and winter high temperature region, can be 25mx5mx2.5m (length x width x height) plastic large gate, plastic film may be retractable,[link widoczny dla zalogowanych], easy ventilation and cooling when the temperature is too high, covered with a layer outside the shelter shed shade net; in the dry climate and relatively low temperature region, can be TOm × 1.5m × 0.7m in the shed, to 2m away from the shade net at the other planes. Shed large shed in autumn and winter is more conducive to heat, moisture, significantly improved survival rate, and the unit Received :1997 -12-241998 on Agricultural Science and Technology 3 large gate area of investment than savings. If long-term use heel shelf, the choice of steel, such as short-term use of available wood, shading material selection 6o% of a 75% shade cloth. 2 bags of nutritional soil nutrient requirements of selected length 14-16cm, width 12-14cm of the bottom side hole of the seedling bag. Banana nutrition nutrition soil should choose suitable composite soil physical requirements, including business requirements of organic rich, breathable, good water permeability, without bacteria and eggs, pH6.0 ~ 7-0 recommended the following formula: According to 1m3 of soil with the proportion of clean, coarse sand 0.5m3, crushed dried mud ponds 0:5 m3, burned soil 2-3 dan, fertilizer 0.1kg. Mix the above ingredients mixed fermentation 1-2 months after the water spray before use. 3 transplanting seedlings to improve survival rate, about 5 days before transplanting of seedlings of tissue culture will be better placed in the local hardening of natural light, light is not too strong to about 10 am the light of appropriate . Transplanting seedlings should meet the following criteria: height 4-5can, expanded leaves 2-3 pieces, dark green leaves. Plant stout, white roots grow well. 1 day before transplanting cup cream nutrition permeable transplanting the seedlings carefully remove from the bottle, attached to the culture medium with water to wash, to remove necrotic tissue and residual leaf sheath, leaf, and then transplanted to the nutrient Cup , pay attention to roots and soil nutrients in close contact. Less root injury, and then set the root water leaching. Note that the size of the seedlings when transplanting separately in different plot planting seedlings to ensure the orderly Chupu same time. 4 days after transplantation management - work to moisture, heat,[link widoczny dla zalogowanych], pest and disease prevention center. Pre-transplant to maintain leaf moisture and humidity mainly based, 7-14 days after transplanting, spray 3-6 times a day, so that the relative humidity in the shed handsome% or so. To eliminate aphids and prevent seedlings susceptible, spraying each 7 ~ 1O days 5OO ~ 800 times a dimethoate solution. After the first piece of new leaves out, shower facilities should be appropriate to add a weak fertilizer to 0.5% to 1% of the compound of water is appropriate. To prevent the seedlings during heavy rain shower and direct light. 5 stems up to hoe when the seedlings off 9-12em, 5-8 leaves long, 5cm wide and above the central leaves can Chupu colonization. Chupu the first 5 days, to gradually pull shade cloth, so that seedlings receiving full sunlight gradually exercise, to improve the adaptability of false Seeding on the field. Note that when the seedlings Chupu strict inspection. Select dark green leaf color, plant robust, growing well, the normal form of no variation in plant colonization, to prevent the disease seedlings, transplanting seedlings to the field and the variation of production. In these sessions, nutrition soil configuration and management is particularly crucial after transplantation. If the lack of nutrition soil in the basal, post-fertilization is not enough, easily lead to The new root production, root rot will result in After transplanting management, pre-transplant days to re-moisturizing soap, and if this stage is not enough humidity can cause seedling leaves soon wilt, and even death. 'If a good grasp of the technology, leave the survival rate of planting more than 90%, and the plants were robust,[link widoczny dla zalogowanych], and high yield for the field and lay a good foundation planting. Inheritance and development of the motherland for the medical,[link widoczny dla zalogowanych], training and well qualified personnel with professional skills of traditional Chinese medicine, the Court continued to students nationwide.
