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.

Abstract

The invention discloses a method for intercropping peanuts and cassava in hilly red soil dry land. The planting mode is characterized in that the safe spatial distance between the cassava and the peanut is at least 40cm; the safe spatial distance between peanuts is at least 40cm; the safe spatial distance between the cassava is at least 400cm; the ratio of the peanut to the cassava is (8.5-9.5):1; soil preparation is performed from December to the January of the next year; the soil is ploughed to great depth for winter; the peanut and the cassava are sowed at the same time; the adaptive phaseis 8-16th, August; and the peanut is subjected to hole sowing; and the cassava is sowed in a manner of inclining 43-47 degrees relative to the ground. The production and income increasing effects areobvious; the yields of intercropped peanuts and pure peanuts have no obvious difference; the yield of the cassava is 1 ton per unit area; the production value is increased by 20.3%; the coordinative development of an energy crop and an oil crop is realized; the light energy utilization of the hilly red soil dry land is obviously improved; and the auxiliary energy conversion efficiency can be improved by 69.42% compared with that of the pure peanut culturing. The method provided by the invention is suitable for the hilly red soil dry land in tropical and subtropical regions.

Description

technical field [0001] The invention relates to dry land intercropping, in particular to a hilly red soil dry land peanut and cassava intercropping method. Background technique [0002] Multi-ripe three-dimensional compound planting represented by interplanting, mixed and interplanting is the main direction of agricultural development in the world today. Improving the multiple cropping index of red soil and harvesting more economic crops is of great significance for the efficient use of limited red soil dryland resources and the increase of total grain production. [0003] Peanuts, also known as peanuts and long-lived fruits, are a kind of Arachis in the leguminous family. The Latin scientific name: Arachis hypogaea is an annual herb. It takes a little more than a month from sowing to flowering, and the flowering period lasts for more than two months. Both yellow sandy loam and red sandy loam with loose texture and good drainage are suitable for peanut cultivation. Cassav...
