How is the red dragonfly planted? High-yield planting technology
Red glutinous rice is a common name for sweet potatoes. It is a food crop in shallow hilly areas. In recent years, the economic benefits and ecological benefits of red carp have been continuously improved, and it has become the preferred industry for farmers to increase their income in many areas. Let's talk about the high-yield planting technology of Hung Hom for reference by the majority of growers. First, the selection and cultivation of strong seedlings 1. Selecting only the best varieties can be selected to achieve the best economic benefits. Can be selected according to the production use: for the commercial (edible) red peony should use high yield, good disease resistance, moderate starch content (about 18%) such as Xu Zishu No. 1, Ning Zi No. 1, Sichuan potato 73 Etc., its palatable taste is good, and the commodity is good; the red peony used for starch processing and feed should use varieties with high yield, good disease resistance and high starch content (about 28%) such as Xushu 18, Xicheng 007 and Chuanshu 164. , Nanshu 97 and so on. 2. Cultivate strong seedlings. Use the sunny and fertile plots that have not been planted with red peony in the previous year. Use the dense film of the mulch (the seedling grows about 20cm and then pull the seedlings to transplant) or the seedlings of the nesting scorpion. In the process of nursery, the manure water is applied more frequently, so that the red saplings that are bred are dense, the vines are thick, the milk is cut, the leaves are thick, the size is moderate, the color is green, the vines have no aerial roots, the roots are thick, and there is no pests and diseases. High production lays the foundation. Second, planting 1. The use of deep ridge cultivation to create loose soil and adequate nutrient supply is the basis for high yield of red carp. Before planting, the rows of red carp should be deep-turned, so that the whole row is loose, so that the red sputum can absorb oxygen and emit carbon dioxide. After deep ridges, the ridges are higher than the ridges (20-30 cm) and wide. (60 ~ 80cm), the furrows should be narrow and deep, which is beneficial to drought prevention and drainage, and is conducive to the expansion of the block. 2. Planting red sorghum at an early date has no obvious growth period, as long as the temperature and humidity are satisfied, it can grow normally. It is recommended that the red carp will be planted in the mangving season, which is conducive to the early growth of the red carp, the long vine, the large area of ​​photosynthesis, and the high dry matter accumulation. Practice shows that when the temperature is above 15 °C, the plant can be increased by 1% to 1.2% every morning for 1 day. Xia Wei can increase the yield by 2.5% to 3% every morning for 1 day. 3. Adopting the strong-nosed seedlings to promote the use of short-growing stalks, short-cut seedlings, two-cut seedlings, and three-cut seedlings. The tip of the seedling has the advantage of the top, the cell tissue is tender, the viability is strong, and there is a strong new root germination and potato-forming ability. Stem segments with petiole detachment and yellowing are not used. Each cut seedling is about 25cm long, in order to ensure deep planting, planting in the soil about 10cm, leaving 10cm outside the soil for photosynthesis, survival and growth. 4. Planting requirements According to different varieties, soil fertility status, early planting period and planting method, etc., reasonable close planting. Generally, 3,000 to 3,500 litters per acre are planted in spring, and 3,500 to 4,000 litters are planted in summer. When planting, it is usually better to use horizontal planting method. Each section (3~5 knots) is planted in the shallow soil layer of 3~5cm below the ridge surface, and the knots can be rooted and knotted. It can make high yield of red dragonfly. Third, fertilization 1. Balanced fertilization can use a large amount of organic fertilizers in planting plots, such as dry mixed fertilizer, human and animal manure, etc., which can improve soil structure, increase soil microbes, increase soil organic matter content, and use straw to return to soil to ensure soil Organic fat content. That is, after the crop is harvested, such as wheat stalks and rapeseed hulls, the rot can also loosen the soil, increase the soil organic matter and nutrient elements, and significantly improve the shape and yield of the red peony. 2. Pay attention to the application of seedling fertilizer in the "Mai-Yu-è‹•" planting mode. Immediately after the corn is harvested, the corn stalks will be cut off to avoid shading and red sputum, which will affect the photosynthesis of red peony. More importantly, the seedlings should be fertilized and seeded, and 30 tons of clear manure water, 30kg of ammonium bicarbonate or 10kg of urea, 10kg of ammonium phosphate and 15kg of potassium sulfate (focusing on light nitrogen and heavy phosphorus) should be applied to the seedlings. It can guarantee enough photosynthesis and synthesize more dry matter to transport to the roots for early crusting and much more. Fourth, field management 1. Weeding In the process of red carp growth, there are many weeds in the field. It is necessary to carry out artificial weeding 2 to 3 times in the field to prevent weeds from absorbing nutrients and shady red mites in the soil. 2. In the process of growth of red mullet, the vine must be raised about 2 times to prevent the growth of red roots. If there is an adventitious root in the red peony, it will affect the dry matter produced by photosynthesis and cannot be completely transported to the roots, which will seriously affect the yield. The vine is not turned over, and the vine process disrupts the normal distribution of the leaves, greatly reducing the photosynthesis ability and photosynthetic product accumulation, and regenerating and consuming nutrients after the stems and leaves are damaged, which affects the normal nutrient accumulation of the roots. Instead, it will lead to a reduction in production. The more times you turn over the vine, the more you cut the production. 3. Prevention and control of diseases and pests Red mites mainly include soft rot and black spot. The prevention and treatment must first select disease-resistant varieties, followed by carbendazim treatment of the seedlings, and again the rotation. Once the disease occurs, it should be immediately symptomatic. Pest control mainly consists of sweet potato hawk moth, leaf armor, tortoise shell, and leaf miner moth. The prevention and control measures are the use of frequency-vibration insecticidal lamps to trap adult insects; the second is chemical control, that is, in early June, early July, and August. In the first half of the year, 25% of the enemy killed 2000 times the liquid spray. Fifth, timely harvest When the vine leaves begin to turn yellow and the temperature is below 20 °C, they can be digging, and premature harvesting will affect the output. The requirements for seeding should be excavated before the end of October (before the frost), and the red dragonfly should be avoided as much as possible during the excavation. The high yield of red carp has a great effect on the total local grain production and animal husbandry development. I hope the above will help you.
