specific Embodiment approach 1
[0023] A method for intercropping peanuts and cassava in hilly red soil dry land, including planting mode selection, that is, planting specifications and requirements, variety selection and cultivation techniques. The cultivation techniques include site selection, site preparation, fertilization, seeding, close planting, weeding and topdressing.
[0024] 1) Planting mode selection: the safe space distance between cassava and peanuts is 40cm, the safe space distance between peanuts and peanuts is 40cm, and the safe space distance between cassava and cassava is at least 400cm, that is, the ratio of peanuts to cassava is 9:1;
[0025] 2) Variety selection: choose peanut variety: Ganhua No. 3, cassava variety: Nanzhi 199;
[0026] 3) Land selection: choose red soil dry land with medium or above medium fertility;
[0027] 4) Soil preparation: From December to January of the next year, the land is deeply plowed for wintering;
[0028] 5) Fertilization: 120 kg of lime per mu when so...
specific Embodiment approach 2
[0033] A hilly red soil upland peanut and cassava intercropping method, basically the same as the specific embodiment one, the difference is:
[0034] The ratio of peanuts to cassava is 8.5:1;
[0035] Select the peanut variety: Youyou 52, the cassava variety: Huanan 8; cassava and the ground are sown at an angle of 43°;
[0036] When deep sowing, apply 130 kg of lime per mu. When sowing peanuts and cassava, apply 13 kg of urea per mu;
[0037] After sowing, use acetochlor with a concentration of 50% to seal the soil according to the dosage of 75ml / mu. ml The amount per mu is sprayed to kill weeds;
[0038] Topdressing 4 kg of urea and 2.5 kg of potassium chloride per mu at the early flowering stage of peanuts; 6 kg of urea per mu at the cassava seedling stage; Potassium chloride 6 kg.
specific Embodiment approach 3
[0039] A hilly red soil upland peanut and cassava intercropping method, basically the same as the specific embodiment one, the difference is:
[0040] The ratio of peanuts to cassava is 9.5:1;
[0041] Choose peanut variety: Yueyou 551, cassava variety: Huanan 205; cassava and ground tilt 47° sowing;
[0042] Apply 140 kg of lime per mu for deep sowing, 14 kg of urea and 12 kg of potassium chloride per mu for sowing peanuts and cassava;
[0043] After sowing, use acetochlor with a concentration of 50% according to the dosage of 65ml / mu to seal the soil. Weed spraying;
[0044] Topdressing 4 kg of urea and 3 kg of potassium chloride per mu at the early flowering stage of peanuts, 6 kg of urea per mu at the cassava seedling stage, 7 kg of potassium chloride per mu at the cassava root formation stage, and topdressing per mu during the cassava root expansion stage Potassium chloride 4 kg.
