Three-dimensional vegetable planting technology

Three-dimensional interplanting of pepper with amaranth: the seeds of amaranth were sown in early and middle april, and then pepper seedlings were planted. Tomato three-dimensional interplanting winter melon: planting tomatoes in the middle and late March, and then interplanting winter melon in early April, with one row of unilateral interplanting per plot. Sugarcane intercropping cucumber: sugarcane is planted around Qingming Festival, and cucumber is planted in early April.

One, pepper three-dimensional interplanting amaranth

It is a three-dimensional planting technology that uses crop growth speed and is different from height and height. It can not only improve vegetable yield, but also reduce rain erosion. Interplanting mainly has the following two cultivation methods.

1. Type 1: Open field pepper intercropping amaranth, pepper can be planted in the first and middle of April, the width of continuous furrow is 1.5m, each furrow can be planted with 3 rows, the plant spacing is 40cm, and the planting amount per mu is about 4200 plants, then the amaranth seeds are evenly broadcast, the sowing amount per mu is 3-4 jin, or the amaranth seeds can be sown first, and then the pepper seedlings are planted. The maturity period of amaranth is the first and middle of May, the yield of amaranth per mu is 1500 jin, and the yield of pepper per mu is about 5000 jin.

2. The second kind: amaranth is planted in the middle shed pepper. Generally, it is cultivated in the middle shed. Pepper can be planted early to the first and middle of March. The planting density is the same as that of open field cultivation. Then amaranth is sown. The maturity period of amaranth is the middle and last ten days of April. The planting season is early and the yield will be relatively high.

II. Three-dimensional interplanting of winter melon with tomato

1. Tomato can be planted in the middle and late March, and then winter melon can be interplanted at the beginning of April. Each row is interplanted unilaterally. According to the plant spacing of 1.5-2m, 300-400 plants can be planted per mu. Tomato growth is dominant in the early stage.

2. When winter melon is put on the shed from May to June, it can be used to shade tomatoes and avoid high temperature burns. Through careful management, the yield of tomatoes and winter melon can reach more than 10000 jin/mu, which belongs to the technology of efficient three-dimensional planting by using growth time difference.

III. Three-dimensional sugarcane intercropping cucumber

1, can use two kinds of crop growth speed of different planting, sugarcane is generally planted around Qingming Festival, after soil preparation to apply sufficient base fertilizer and then seed, general ridge width of 1.5m, seed row for 2 rows, covered with plastic film can be, cucumber can be selected in early April planting, each ridge side planting for 1 row, plant spacing of 30cm, planting about 1500 plants per mu.

2, or can also be every other ditch, in two rows of a variety of rows, and then cross the scaffolding, if the sugarcane base fertilizer foot, row spacing, good ventilation, and then add plastic film coverage, cucumber growth will be faster in the early stage, cucumber maturity for April-May, yield per mu can be as high as 3000-4000 jin, and the growth of sugarcane has little impact.

3. Using the growth characteristics and morphological characteristics of different varieties of vegetables for three-dimensional intercropping can make full use of space and greatly improve unit area and yield.
