I. Vigorously develop Qiu Yangchao (I) Variety selection Select good middle and early maturing varieties such as Chuanxiongzao, Chuanxiong 4 and Chuanxiong 56. (2) Timely sowing In view of the cool climate conditions of the Chinese wolfberry, the sowing date is generally determined to be stable below the daily average temperature of 25°C. (3) Seed Potato Disposal Acacia generally has a dormancy period of 2-3 months. It is necessary to determine the treatment method of seed potato according to different regions. Generally, it is necessary to adopt the method of seeding with buds. 1. In the Pingba area, the spring-infested oysters in the Pingba area were used as seedlings of the autumn yam. They had passed a dormancy period when sowing, and most of them had germinated and should be planted with whole potatoes. 2. In the areas above the Mid-levels, the species that have been preserved by the spring oysters for the autumn yang species do not pass the dormancy period. If they are planted directly, they are not easy to germinate, and germination must be carried out before sowing. Germination treatment method: Choose a cool and cool place with low temperature, cover and cover with wet sand in the house, stack 3-4 layers, and cover the straw to keep the moisture on the surface, and maintain the temperature at about 20°C. When the bud grows to 1-1.5 cm, take it out and put it in the cool outdoor place for 1-3 days to sow. (D) sowing and field management Paddy field, no-tillage, straw-covered cultivation When harvesting rice, it is necessary to cut the rice with mud, and keep the piles of shallow rice. Open the deep trenches in the drainage direction of the paddy fields and use them as a high compartment to prevent flooding. When sowing the potatoes, the seed potatoes should be placed on the topsoil of the field by hand with a spacing of 33 cm and a spacing of 23 cm, so that the seed potatoes are in close contact with the soil. In general mu application of urea 10-15 kilograms, superphosphate 25-30 kilograms, plant ash 100 kilograms. Each acre of artichoke is covered with straw of 1.5-2 acres of paddy fields, and the cover grass thickness reaches 10-17 centimeters. The grass cover direction is vertical to the straw and the car ditch, and the grass tip uniformly covers the entire car surface. 2. For ridge cultivation, shallow-cultivation cultivation has a higher topography. The well-drained land is used for ridge cultivation. If drought occurs during sowing, it will be covered with clear water. Shallow cover thin cover, sooner or later sowing, to prevent bad seedlings. After replanting the base fertilizer and increasing the application of phosphorus and potassium fertilizers, the seedlings should be raised early after emergence, combined with fertilization after the seedlings, and cultivated and weeded. After the heavy rain, the soil should be ploughed and loosened to prevent soil compaction. 3. To strengthen the prevention and treatment of late blight in the middle and late stages of the discovery of central disease strains, and immediately remove the destruction, can be used 100 times "Bordeaux liquid" or 600-800 times "dance Sen zinc", spray every 7-10 days for prevention and treatment. Second, strengthen the demonstration and promotion of autumn fodder for green fodder (I) Selection of suitable varieties In the existing promotion varieties in our province, select the varieties with vigorous growth of stems and leaves, such as Nanshu 99, Sichuan 383 and so on. (b) Strive for early sowing and early planting. Where fields are planted with autumn red plants, they should be planted as early as possible if they are not subject to the restrictions of the former crop. If there are previous works, they should be harvested while digging the planter and planting red plants. In the early and middle rice fields of autumn red rice dumplings, the rice was drained in time after being scattered. After the harvest, deep trenches were planted and planted to make the drainage unimpeded. This prevented the occurrence of waterlogging, and used the early maturing dry land to plant autumn red maple. (c) The appropriate increase in planting density is generally net planted 6000-7000 acres per plant, the spacing of 16-20 cm, row spacing is 60-70 cm. In the season of high temperature and strong sunshine, the autumn and winter yucai must be planted on cloudy days or on sunny evenings. After planting, the nests should be filled with clear manure water, and 40-50 acres should be selected. And covered with draft stalks to prevent sunburn caused by wilting or dead seedlings to ensure Miao Qimiao. (IV) Strengthening field management The autumn plover is mainly based on harvesting vine leaves. Appropriate adjustments are made in the management of fertilizer and water, and the amount of nitrogen fertilizer is appropriately increased. After planting and survival, it is necessary to remove the covering in time, apply sufficient seedling fertilizer, apply 30-40 tons of pig manure water, add a small amount of nitrogen fertilizer to raise seedlings, and clean the drainage ditch to promote the growth of the vine. About 20 days after planting, weeds should be removed. According to growth conditions, seedlings should be treated as appropriate. In the middle and later stages, 100 grams of potassium dihydrogen phosphate per acre, plus 500 grams of urea and 50 kg of water, spray evenly throughout the field, spray once every 5-7 days, can spray 2-3 times. 3. Appropriate promotion of the selection of fall soybean (A) varieties: Chengdou No.11, Zhechun No.3, Chengdou No.9, Gongdou No.5, Gongdou No.10, Chuandou No.6 and other medium-maturing varieties. (2) Timely sowing and planting of autumn soybeans in paddy fields with good planting should use high-lying, well-drained blocks of early-middle rice or hybrid rice farming. After the rice is harvested, it will be drained in a timely manner and the no-tillage cultivation will be conducted. The planting density is 15,000-20000 plants per mu, the spacing is 30-50 cm, the spacing is 17-30 cm, 5-6 plants per litter, and 3-4 plantlets. (C) to ensure adequate fertilizer and water, when sowing, per acre to apply 20-30 tons of pig manure water, 15-20 kg of superphosphate, dry conditions can be 1000-1500 kg of dry manure as a base fertilizer. When the seedlings grow to 2-3 leaves, 5-6 kilograms of urea or 15 kilograms of ammonium bicarbonate are used, and the seedlings are diluted 20-30 for pig manure. In the early flowering period, extra-root fertilizer was applied with a 2% potassium dihydrogen phosphate solution to increase the number of pods and grain weight per plant. (D) timely treatment of insect sowing after the Mu with 20% methyl isothione 300-400 ml mixed with toxic soil 20 kg spread soil surface, the prevention and control of fleas, mites and other underground pests. 2-3 leaves and the early flowering period, with the use of emulsifiable concentrates of emorydoerythrin or 30-40 millilitres of the enemy, spraying 50 kilograms of water to fight against pests such as leguminous fly, bean leaf mite, aphids, bridge-building insects, and bean worms.
