The high-efficiency planting mode of “Peanut-Single-season Late Rice†was investigated to improve the soil environment and increase the soil fertility due to the rotation of water and drought, so that the yield per single crop of rice increased by 40-50 kg per mu, and the output value increased by about 100 yuan, which greatly improved the yield of rice planted in two seasons. . The high-efficiency cultivation technique of the "peanut-single-season late rice" planting mode is now introduced as follows.
1. Choose excellent varieties
According to the market demand and the geographical environment characteristics of Ganzhou City, the peanut variety chooses the “small red hairâ€, “Tianfu No.3, and “Tianfu No.10†as the main varieties. The rice varieties choose the late rice with good resistance and good rice quality. The new combination of japonica rice “Zhongzheyou No.1†and “Yueyou 938†can meet the growth requirements of peanuts in the season and meet the high yield requirements of late-type rice.
2. Seeding at the right time
Taking advantage of the early rise in spring temperatures, planting early-maturing peanuts can generally start planting in March and mid-March. Premature sowing is not conducive to the growth of peanuts due to unstable soil temperature, and does not meet the requirements of high yield and high efficiency; too late sowing can not reflect the advantage of early sowing, and at the same time affect the growth of late rice. The late rice should be determined according to the characteristics of “Zhezheyou No.1†and “Yueyou 938†and the harvesting period of peanuts. Generally, the seeds are planted about 20 days before the peanut harvest .
3. Do a good job in field management
Peanuts are sun-dried for 1 day before sowing, and are sown with the seeds at the time of sowing. When the soil is prepared, the base fertilizer is applied. Generally, 30 kg of ammonium bicarbonate and 25 kg of superphosphate are used. When the ditch is planted, 25 kg of compound fertilizer with 15% of nitrogen, phosphorus and potassium is used as seed fertilizer. Apply to the seeding ditch, but must be kept at a certain distance from the peanut seeds to avoid affecting the emergence. The planting density is generally controlled at about 6,000 plants per mu. Immediately after sowing, spray herbicides, using acetochlor (Wernes) 50-75 ml of water plus 35-50 kg of fine spray, or 33% of Shi Tian 200-300 ml of water plus 50 kg of fine spray, then cover the mulch . After sowing, we should pay attention to observe the emergence of seedlings, and timely release the seedlings to prevent the peanuts from suffocating. Spray 0.2% ammonium molybdate and 0.2% borax solution once in the first half of peanut growth to increase the seed setting rate and increase the yield; in the later stage of growth, pay attention to prevent premature aging, 0.5% urea plus 0.2% potassium dihydrogen phosphate solution Spray once. In addition, for the field with a long trend in the upper part of the ground, use 15% paclobutrazol 20-30 g from the initial flower to the full bloom period, add 20-40 kg of water, or spray 30 times with 30-50 g of B9 plus 45 kg of water. It promotes the plant to be short and strong, which is conducive to fruiting. However, it cannot be applied to fields with weak growth.
The amount of rice used in the field is 0.7 kg per acre, and it is sterilized by soaking seeds with "402" or "making 100 grams" before planting. The age of dry nursery is controlled at 25 to 30 days, and the age of semi-dry breeding is about 25 days. When the seedlings are one leaf and one heart, spraying 300 mg/kg of paclobutrazol promotes the seedlings to be short. Datian planting plants are 20 cm × 20 cm in length, and 1.2 to 15,000 bushes per acre. Fertilization adopts the strategy of pre-heavy and light-replenishing, and carefully apply panicle fertilizer to prevent lodging in the later stage. The application rate of nitrogen fertilizer can be 10%-20% less than that of similar varieties, generally based on base fertilizer, 20-30 kg of ammonium bicarbonate and 20-25 kg of superphosphate per acre. After 5 to 7 days after the insertion, the topdressing can be carried out with 8 kg of urea, 7 kg of potassium fertilizer and 30 g of 30% pure lycopene for chemical dressing and chemical weeding. Keep 1 inch of field water, let it dry naturally and then water. When the number of seedlings reaches about 150,000, the field will be drained in time. It is not appropriate to lighten the field, to control the highest number of seedlings to increase the rate of ear formation, and to promote root development and enhance the late lodging resistance. In order to increase the yield, it is necessary to prevent the water from being cut off too early before harvesting, and harvest at the time of nine ripening.
4. Do a good job in pest control
Due to the cultivation method of water and drought rotation, peanuts generally have few pests and diseases, and only a small amount of cockroaches, mites and leaf beetles are harmful. In the production, the former can be applied with 50% phoxim 1000-1500 times solution, and the latter two can be controlled with 10% imidacloprid 3000 times solution. Two new varieties of late japonica rice, "Zhezheyou No.1" and "Yueyou 938", have good resistance to stress, are more resistant to rice blast, moderate to bacterial blight, and susceptible to rice smut. Therefore, in addition to the prevention and control of aphids, rice leaf roller, rice blast and sheath blight in production, the prevention and control of rice smut should be especially strengthened. It is necessary to control the drug twice, when the whole field is 30% to 50%. When the leaves of the stems are taken out, the medicine is sprayed once, and the medicine is re-medicated once every 7 days, and the Jinggangmycin can be sprayed with 300-400 ml of water per acre. Pay attention to the inspection and prevention of bacterial diseases in time after the typhoon.
Active Pharmaceutical Ingredients
Active Pharmaceutical Ingredients(API) refer to the raw materials used in the production of various preparations. They are the effective ingredients in the preparations. They are various powders, crystals, extracts, etc., prepared by chemical synthesis, plant extraction or biotechnology, but Substances that the patient cannot take directly. API is intended to be used in any substance or mixture of substances in the manufacture of pharmaceuticals, and when used in pharmaceuticals, it becomes an active ingredient of the pharmaceuticals. Such substances have pharmacological activity or other direct effects in the diagnosis, treatment, symptom relief, treatment or prevention of diseases, or can affect the function or structure of the body. According to its source, active pharmaceutical ingredients are divided into two categories: synthetic chemical active Pharmaceutical ingredients and natural chemical active Pharmaceutical ingredients.
