Sesame disaster-reduction high-quality sowing method

Abstract

The invention discloses a sesame disaster-reduction high-quality sowing method. The sesame disaster-reduction high-quality sowing method includes the following steps of 1, soil preparation, wherein after previous crops are harvested, farmland is subjected to soil preparation; 2, ditching and ridging, wherein ditching and ridging are conducted on the farmland obtained after soil preparation, inverted trapezoidal ditches are made, the width of the tops of the ditches is 30-40 cm, the width of the bottoms of the ditches is 18-22 cm, the vertical depth of the ditches is 18-22 cm, the ridge bed faces of ridges are in a turtle back shape, and the width of the ridge bed faces of the ridges is 170-180 cm; 3, base fertilizer application; 4, sowing and earthing, wherein hole sowing is conducted on the ridge face of each ridge, the hole spacing is 12-20 cm, the line spacing is 30-36 cm, and then earthing is conducted. By adopting the sesame disaster-reduction high-quality sowing method, accuratesesame sowing can be achieved, the quality of sowing and seedling emergence is improved, labor investment for thinning and establishing is reduced, waterlogging during sesame growth is effectively prevented and controlled, and thus the sesame yield is increased.

Description

technical field [0001] The invention relates to a high-quality sowing method of sesame for disaster reduction, and belongs to the technical field of crop production. Background technique [0002] Sesame( Sesamum indicum L.) belongs to the flax family, herbaceous plants, high-quality oilseeds and special economic crops that are widely cultivated and utilized in the world. Sesame has a long history of cultivation in my country, lasting more than 2,100 years. It is rich in unsaturated fatty acids, vitamin E, sterols, sesamin and other nutritional functional substances, and has various uses such as food, health care, and medicine. It is loved by Chinese consumers. The development of sesame industry in suitable regions and soils has broad economic and social prospects. With the people's longing for a high-quality life, the demand for sesame in my country has been increasing in recent years, and it has become the world's largest consumer and importer. However, the total domes...

Problems solved by technology

[0003] Summer sowing in the main sesame producing areas of Jianghuai in my country is generally from late May to early June. It is in the rainy season and there is more rain. Sesame production is extensively sown in the field, mostly broadcasting. Seedlings, lack of seedlings and broken ridges and other problems not only require more labor for thinning and setting seedlings, but also increase production costs, and are not conducive to high yield

In addition, the growth period of sesame is short (about 90 days), and it is under the condition of high temperature and high humidity in summer (June to August). The soil drainage in the traditional planting method is not smooth, and it is often threatened by waterlogging, which aggravates the disease and causes serious damage. Production reduction, 15-30% production reduction in one move, 60-80% production reduction in extreme years, some fields may lead to failure of harvest, and also cause reduction of sesame quality, oil content reduction of 4-10%, and poor commerciality. Therefore, research is urgently needed Provide a method of soil preparation and sowing to achieve the effect of disaster reduction and production increase
