Problems solved by technology

[0006] The present invention aims to solve the problems of difficulty in returning straw to the field, unbalanced planting and breeding, deterioration of soil physical and chemical properties, aggravation of diseases and insect pests, increased input without increasing production, and unreasonable row spacing configuration under traditional corn-peanut intercropping under the existing continuous cropping mode of corn and peanuts. Due to the low utilization rate of heat resources, the "double increase" of corn and peanut production has been achieved through the three-dimensional ecological interplanting method of corn and peanuts, which meets the major strategic needs of the national planting structure adjustment under the new normal

specific Embodiment approach 1

[0025] Specific implementation mode one: the cultivation method of corn and peanut composite three-dimensional ecological interplanting in this embodiment comprises the following steps:

[0026] 1. Selection of improved varieties: corn varieties are selected with high quality, high yield, wide suitability, high resistance, and density tolerance; peanut varieties are selected according to local planting habits, growth period, and ecological conditions with great potential for increasing production, appropriate growth period, high yield and good quality. Variety;

[0027] 2. Site selection and site preparation: Select loam or sandy loam soil with loose cultivation layer, deep active soil layer, neutral acidity, good drainage and fertility characteristics; the general requirements for site preparation before sowing are: loose, finely crushed, non-compacted, The amount of water is moderate, the soil moisture is 65% to 75% of the field water holding capacity, and the drainage and i...

specific Embodiment approach 2

[0034] Embodiment 2: This embodiment differs from Embodiment 1 in that: in step 1, the corn variety is the special high-starch variety “Liangyu 66”; the peanut variety is the special high-oil content variety “Baisha 1016”. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0035] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: in step four, the distance between the plants of corn is 11.8-15.0 cm, and the distance between plants of peanuts is 20 cm. Others are the same as in the first or second embodiment.

Abstract

A corn and peanut complex three-dimensional ecological intercropping planting method relates to a planting method for corns and peanuts. The corn and peanut complex three-dimensional ecological intercropping planting method can solve the problems that in the mode of long continuous cropping of corns and peanuts, straw reapplication is difficult, planting is out-off-balance, physic and chemical properties of soil deteriorate, pests and diseases become serious, the investment is increased but the yield is not increased, row spacing configuration is not reasonable during the conventional intercropping between the corns and the peanuts, and the utilization of light and heat resources is low. The method includes the following steps of: 1) good seed selection; 2) land selection and soil preparation; 3) soil testing and formulated fertilization; 4) field arrangement optimization; 5) seeding and reasonable close planting; 6) fine field management; 7) straw reapplication; and 8) crop rotation, fallowing and land maintaining. Many years of tests show that the yield of the corns can be increased by 2.0% to 8.0% more than that of the conventional planting method; compared with the conventional planting method, the yield of the peanuts can be increased by 1800 to 2200 Kg / hectare in average. The corn and peanut complex three-dimensional ecological intercropping planting method can be applied to the field of crop planting.

Description

technical field [0001] The invention relates to a method for cultivating corn and peanuts. Background technique [0002] Maize (Zeamays L.) belongs to the Poaceae Maize genus, is an important grain, economy, and feed crop, and occupies a very important position in my country's grain production and national economy. Scientific research and corn production practice have proved that the planting method is one of the key factors affecting the yield level. [0003] A reasonable intercropping model can effectively use light, heat, water, nutrients and other resources to increase the yield and benefit per unit of cultivated land area. It plays an important role in agricultural production and is also an effective way to develop modern agriculture and circular ecological agriculture. Among them, the three-dimensional ecological interplanting of corn and peanut is an excellent intercropping model. The current corn-peanut intercropping technology mainly adopts the traditional mode of...
