Leek regeneration and delivery ability are very strong, can be rooted for many years, many harvest. Its young leaves, leeks and leeks are products that can be eaten fresh or processed. Amaranth, with its strong cold tolerance and wide adaptability, can be supplied in all seasons in Yunnan. With the improvement of the people's living standards and the demand for export, the production and consumption of the yellow bud leeks is increasing day by day, and they are required to meet the standards for pollution-free green food. First, the breeding method: You can use the seed to breed, you can also use the ramets to breed. The trifoliate propagation is to dig up the root of the old loquat to be renewed, cut the old roots and the upper leaves of the lower part, and plant them at a certain spacing after the wounds heal. Although this method can avoid the procedure of raising seedlings, due to the longevity of perennial roots, the growth of the plants is weak and the number of tillers is also small, so seed propagation is still dominant. Seed breeding, first select high-yield and disease-resistant varieties such as Rhizoma Imperatae, Pingjing No.2, No.791 and Xueye No.4, soak them with warm water of about 55°C before sowing, then soak in warm water for 12 hours, and then 20-25. The germination was carried out for 2 to 3 days under the temperature condition of °C, and the seeds were ready for germination. Spring sowing can be sown during the sowing period before and after the Ching Ming, before and after the cold sowing in autumn. Seedbed should be loose and fertile, well-drained loam or sandy loam, full base fertilizer made of sorghum, about 300 grams per acre sow, you can plant an acre of Daejeon. Second, the choice of planting: Although the leeks are perennial root plants but if you do not pay attention to the rotation, continuous cropping is too long the pest damage is serious, poor plant growth. Therefore, reasonable rotation should be promoted to properly conduct crop rotations with water crops such as melons and lotus roots. After the current harvest, deep-turning and applying fully decomposed farmyard fertilizer 3000-4000 kg, compound fertilizer 30 kg. When the seedlings have 18 to 20 centimeters in height, they can be planted or planted in rows of 30 to 40 cm. Third, field management: After planting and survival, according to soil moisture and plant growth, we should carry out cultivating and weeding, timely irrigation, and top dressing. Topdressing can use dilute human urine or urea to pour water, in order to allow the new plant to grow vigorously, accumulate more nutrients, the general cultivation of the year does not harvest, until the next year when the leek has 25 to 30 cm high can be harvested. Fourth, shading and softening: the traditional yellow bud brewing system, there are horse dung, straw, crop straw, weeds and other materials, but the glutinous yellow commodity is poor, not sanitary. It is now generally used as a scaffold to cover weeds, leaves, and black membranes. The height of the shed is 60 to 70 cm. Before planting the leeks, ten centimeters from the surface shall be taken to cut the leaves. The leeks may be left at about 15 centimeters. After the wounds are healed, they are fully watered, topdressed and then covered with weeds, straw, and cilantro. Light prevails. If there is little covering material, a black plastic film can be placed on it to reduce the weight and keep warm in winter. The temperature in the booth is maintained at 15 to 20°C. Exhaust air exceeding 25°C is required to reduce the temperature and humidity. In general summer and autumn can be harvested as long as 20 to 30 days, while in winter and spring it takes 40 to 50 days. A piece of ground leeks can only be picked 1 or 2 times a year. After harvesting the yellow bud leeks, the covering was removed and the rhizosphere soil was loosened. After the new leaves were sent, they were watered in time, topdressing and cultivating the soil to restore the vitality of the leeks, thereby laying the foundation for the next crop yield. In the application of fertilizers for pollution-free leeks, farmyard manure should be added, and unconsumed human urine and nitrate nitrogen fertilizers should be prohibited. V. Pest Control Diseases: The damage caused by pseudo-stems and bulbs is heavy, and flower-buds can also be infected. It is a dark green, water-soaked lesion and is a fungal disease. Pay attention to crop rotation and drainage. The agent can be rooted or sprayed with 600 times solution of mesogenic copper wettable powder or 600 times of 60% aluminum phosphate aluminum. Rust: It can be sprayed with 15% triazole quinone 2000 times or 25% rust rust 1000-1500 times. Botrytis cinerea: mainly to harm the leaves, available 65% metalaxyl 1000 times, 50% speed Keling 1500 times liquid prevention. Locust: 40% of dimethoate EC 1000 times, 50% anti-influx 1500 times liquid control. éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† éŸè›† Regardless of which pesticide is used, it must be used according to the concentration and method of use instructions, and be careful not to use it for 10 to 15 days before harvesting.
