How far should I plant a sesame seed?

Sesame is an annual erect herb with high application value. Sesame is one of the main oil crops in China. So how far is it to plant a sesame seed?

1. Cultivation techniques of sesame

Sesame stem erect, less shaded area, sesame is often used to mix with dwarf crops. For example, mixed or intercropped with sweet potatoes, peanuts, soybeans and other crops. Generally, make a row of sesame seeds in 1-2 rows of sweet potato or every 2-4 rows of peanuts. Sesame is more drought-tolerant, while legumes are more moisture-tolerant. Mixed cultivation of sesame and legumes is beneficial to prevent drought and waterlogging.

1. Land preparation

In the case of more soil moisture, the soil can be fine raked vertically and horizontally after ploughing, and raked to cover seeds after sowing; in the case of less soil moisture, sowing and covering seeds can be raked immediately after raking, and soil moisture conservation can be suppressed. Sesame is afraid of stains, and the growth period is in the period when Rain Water is more, so it is necessary to make a border-about 2-3 meters wide when a single kind of sesame is planted, and to open a good border ditch, waist ditch and perimeter ditch in order to drain and irrigate in time.

2. Sowing seeds

The suitable sowing time of summer sesame is from late May to early June. The suitable sowing time of autumn sesame is early or middle July, and it can be late in late July under the condition of good heat.

The amount of seed used per mu is 400 g for sowing, 350 g for strip sowing and 250 g for on-demand sowing.

There are three sowing methods: on-demand sowing, sowing and strip sowing.

3. Fertilization

The key point of fertilization for sesame lies in the grasp of timing and methods, requiring that seedling fertilizer should be "early", bud fertilizer should be "skillful", flower fertilizer should be "heavy", and attention should be paid to the coordination of nitrogen, phosphorus, potassium and trace elements, and the combination of organic fertilizer and inorganic fertilizer. to achieve the matching of base fertilizer, seed fertilizer and topdressing fertilizer, scientific fertilization, to achieve early development, stable growth and no premature senescence of sesame.

In addition, it is also necessary to do a good job in the management of seedling determination, intermediate ploughing and weeding, irrigation and drainage.

Second, it is better to plant one sesame seed as far as possible

Generally, the width of the box is 1.5-2m, and the width of the box is about 30cm, but the planting density of sesame is also related to the sowing time, variety, soil fertility and other factors.

The planting densities of summer sesame single rod varieties and branched sesame varieties were 8000-10000 plants per mu, 6000-8000 plants per mu, 10000-15000 plants per mu and 8000-10000 plants per mu for autumn sesame varieties.
