Water-supplying method for ensuring tobacco seedling drought-resisting transplanting through rainwater accumulating

Abstract

The invention discloses a water-supplying method for ensuring tobacco seedling drought-resisting transplanting through rainwater accumulating. The method includes the steps that in February every year, a tobacco field with inclination is selected, and ridging is performed on the slope of the tobacco field; soil of ridge bodies is pounded, field ditches are dredged, plastic films mulch the adjacent ridge bodies and field ditches and are pressed tightly, and a W-shaped rainwater accumulating lawn is formed ; a pit is dug at the lowest place of the tobacco field, and pesticides are spread at the bottom and the periphery of the pit, so that underground insects are prevented from damaging the tobaccos; then, mulching of plastic films is performed, anti-leakage treatment is performed on the mulching plastic films, and the situation that water leakage does not exist is ensured, so that a water reservoir is formed; the rainwater accumulating lawn and the water reservoir form a simple rainwater accumulating pool of the tobacco field. By the adoption of the method for ensuring the tobacco seedling drought-resisting transplanting through the rainwater accumulating, for regions where tobaccos are suitable for being planted, but the tobaccos often suffer spring drought, in the beginning and the middle of March and April, a small amount of ineffective rainfall for several times is effectively accumulated. Therefore, when the drought-resisting transplanting is performed on the flue-cured tobaccos in advance in due time, the problem of required water supply is solved, so that yield and quality of the flue-cured tobaccos are improved.

Description

technical field [0001] The invention relates to a rain-collecting flat and a water storage tank, and furthermore, belongs to the technology of ensuring drought-resistant transplanting water for tobacco seedlings by collecting and storing rainwater. Background technique [0002] Qianxinan Prefecture, Guizhou Province has an area of ​​2.8 million mu, which is one of the best areas for producing high-quality characteristic tobacco leaves. The best flue-cured tobacco transplanting period in Qianxinan Prefecture is from late April to early May, but during this period, spring drought is severe all year round, often with ineffective rainfall with rainfall <15mm, and the effective coverage area of ​​smoke water projects constructed in recent years is less than To 30% of the tobacco planting area in that year, the tobacco seedlings with large areas all the year round cannot be transplanted timely and early at the best transplanting period, which seriously restricts the improvement...
