Embodiment Construction

[0026] The present invention fully utilizes the natural precipitation to carry out direct seeding and drought-resistance and water-saving cultivation technology of rice, which is implemented in Chuanshan Town and Baipeng Town where conditions are not so good in Liujiang County, Guangxi.

[0027] In all parts of the South, the general rule of the impact of precipitation at various levels on crops is: in the main growing season of crops, the critical period of crop water demand is often within a certain ten or several ten days, and the relationship between ten-day precipitation and crop growth and development is shown More closely, that is, the amount of precipitation in ten days is crucial to the growth and development of crops. Precipitation in ten days: less than 10 mm, the lack of water in farmland is serious; less than 30 mm, insufficient water; 30-50 mm, which can meet the water requirements of crops, 100-150 mm, excessive rain; more than 150 mm, There will be floods.

Abstract

The invention discloses a drought resisting and water saving cultivation technique for performing direct sowing on a dry paddy field by fully using natural precipitation, which is used for adjusting the growth period of paddy rice according to water requirements at each growth and development stage of the paddy rice and statistical data of historical meteorological data for a natural precipitation rule of every local ten days, so that each growth and development stage of the paddy rice is matched with the natural precipitation of every local ten days and corresponding comprehensive technical measures are taken to fulfill the aim of resisting drought, saving water and stably increasing yield. The cultivation technique changes a traditional paddy rice cultivation mode, finishes one season of paddy rice production only by using natural precipitation without soaking seed, raising rice seedlings and transplanting or needing irrigation and plowing and can directly perform direct sowing production on the dry paddy field in a dry land or a non-dry land. Therefore, the technique saves irrigation water, lowers costs of seedlings, transplanting, drought resisting, water pumping, plowing and the like, saves labor, cuts down expenditures and increases income and is favorable for realizing increment of grain production and rural incomes and agricultural efficiency and realizing resource conservation, energy conservation and emission reduction.

Description

【Technical Field】 [0001] The invention relates to a crop cultivation technique, in particular to a drought-resistant and water-saving cultivation technique that fully utilizes natural precipitation to carry out direct seeding of rice. 【Background technique】 [0002] my country is a large agricultural country. Agricultural water accounts for 80% of the total water consumption, and rice is the crop that consumes the most water, accounting for more than 45% of the total water consumption in the country. Traditional rice cultivation requires a lot of water to irrigate from seedling raising to transplanting. Once water is lacking, rice yield will be affected and even cultivation will not be possible. In recent years, global warming has caused abnormal weather changes, and droughts and water shortages have become more serious. In 2007, a large-scale and regional drought occurred throughout the country. In recent years, the country's drought-affected area has exceeded 200 million mu. Ac...
