This model implements a paddy-upland rotation to improve the soil structure of the plough layer. At the same time, we will make full use of land, light and heat resources to increase the multiple cropping index of cultivated land. The annual output of arable land is 2040--2400 yuan (including peanut 900--1000 yuan, rice 540--600 yuan, and potato 600-800 yuan). (I) Spring Peanut Cultivation Technology 1. Selection of improved varieties: Select high-yield varieties such as vertical or semi-upright type, such as Quanhua No. 10, Emu No. 71, No. 1 white sand, No. 4, Butter 17 and so on. 2, suitable sowing: In late March, if covered with a special peanut film cultivation, sowing date can be as early as March 15 or so. When the 5 cm deep soil layer stably passes 15°C, it is robbed or selected for planting. The sowing is completed before the clearing. 3, Shizujifei: rational dense planting, soil preparation must be full-time full-time base fertilizer, usually Mushi soil fertilizer 5000 kg, standard nitrogen fertilizer 30--40 kg, superphosphate 40--80 kg, potassium sulfate 10- - 15 kg. After intensive cultivation, the whole planting spurs have a width of 1.1 to 1.3 meters. The smashed soil is crushed, and the peanuts on Panasonic are smashed. The two rows of pods are planted in a row with a spacing of 30 cm and a depth of 5 cm. 4, field tube points: 1 in the Qimiao time to check seedlings fill deficiency. 2 Weeding and weeding requires "head-depth, second-pass shallow, and three-time fine." The first cultivator is about 7 days after the emergence of peanuts. The second cultivator should be changed from purple to green in the internodes of peanut twigs, and shallow pods should be used when the secondary branch has grown. The third cultivator combined with soil, should be careful. After the peanuts are sealed, they enter Fuxi, which is often hot and rainy, and weeds grow. It can be removed 1–2 times before harvesting. 3 When the seedlings grow to 4- to 5-leaf, 4 to 5 kilograms of urea should be allocated with water and used as a branching fertilizer; after 7-10 days of flowering, mu should be applied with lime of 20--25 kg; In the later period, the leaves were sprayed 1-2 times with 2% potassium dihydrogen phosphate. 4 scientific management of water, horse water should be irrigated during drought, low-lying land should be drained in time. 5 pay attention to the prevention of bacterial wilt, leaf spot, aphids, Spodoptera litura damage. (2) Late rice cultivation techniques 1. Selection of counterpart varieties (combination): such as 46 combination, Shanyou 82, etc. 2, timely sowing, to ensure that late rice is safe and full of ear, according to the characteristics of the species (combination), mountain arrangements before September 15th ear, the plains arranged before September 20 ear, require the completion of sowing by the end of June. 3, nurture strong 秧 秧 推广 秧 秧 秧 秧 秧 秧 秧 秧 秧 推广 推广 推广 推广 推广 推广 推广 推广 推广 推广 推广 推广 推广 推广 推广 推广 推广 推广 推广 推广 推广 推广 推广 推广 推广 秧 秧 秧 秧. Sowing to Qimiao to keep the nutritious soil moist, when the seedlings grow to two leaves and one heart, the implementation of dry education; in one leaf and one heart, may be appropriate to apply decomposed human urine for weaning fertilizer; cast 2-3 days before, can be acres With 5 kg of urea, add water, and apply 10 times for one delivery. 4, rational close planting, strengthen field management. Generally, it is advisable to plant 1.8-2.0 million bushes per mu, and throw 70% to make up 20% first. Finally, 10% of the seedlings and the gills managed by the ditch should be used for intercropping and thinning, and the seedlings should be evenly distributed. On the fertilizer pipe, the basic fertilizer should be re-used, with little or no application of fertilizer and skillfully applied to panicle fertilizer. Generally 11 to 12 kg of pure nitrogen is applied in Mushi, and the ratio of N:P:K is 1:0.4:0.8, nitrogen fertilizer accounts for 60 to 70% of basic fertilizer, and phosphate fertilizer accounts for 80 to 90%; topdressing N fertilizer accounts for 20 to 30%, and K fertilizer is inserted. Within 7-10 days, one-time application was performed to see if the seedlings applied balanced fertilizer and clever application of panicle fertilizer. On the water pipe, the principle of “thin skin, early roasted, semi-dry†should be followed. When throwing oysters, shallow water should be promoted after shallow water, when the number of hybrid mu pods reaches 200,000 seedlings, and the number of conventional rice cultivars per mu is 260,000. About half of the seedlings were cooked in the field, and after the fields were rehydrated, semi-dry type water pipes were used. In terms of pest control, the pests of rice, mosquitoes, grazers and rice planthoppers are highlighted. (C) potato cultivation techniques 1, selection of seed, appropriate sowing, appropriate dense planting. Promoting the cultivation of detoxified potatoes such as Kexin No. 3 and Chunshu No. 4 and sowing in late December, planting density, generally 1.33 meters wide (with ditch), spacing 0.33 meters, planting two rows, one kind of potato, 3600 acres. - 4000 strains. 2. Rational fertilization and water management: Apply enough basic fertilizer before sowing, apply 15 kg of ammonium bicarbonate in Mushi, 20-25 kg of calcium, magnesium, phosphorus; 20 kg of potassium sulfate and 3,000 kg of mixed fertilizer; Seedling period and hair growth period in each mu Apply 10 kg of ammonium bicarbonate and 5 kg of potassium sulfate twice to promote growth above the ground. In the late stages of potato growth, field drainage should be done. 3, do a good job of pest control: should take comprehensive prevention and control measures to prevent bacterial wilt, ring rot and other diseases, timely control of field worms.
