Abstract
The invention discloses a method for preventing cold damage to rice, preparing dry weed or other burning material around paddy field, burning the material when there is continuous overcast sky to make smoke and form artificial cloud layer to prevent low temperature light emitted by sunlight until high temperature light is emitted. This invention can maintain needed temperature in growing process, and is good for plump seed and guarantee stable and high productivity. The technology of this invention is simple and suitable to spread.
Description
Technical field
The present invention relates to a kind of method of preventing low-temperature cold damage of rice.
Background technology
The paddy rice natural low temperature damages to plants caused by sudden drop in temperature the low temperature light that derives from sun emission.The sun is launched multiple light, comprising high temperature light and low temperature light, and the many heat content of its high temperature light, and low temperature light is quite different.People can feel that low temperature light is respectively before the The sun came up and after setting, its reason is that low temperature light ratio high temperature light disperses more.Sunshine forms the sunshine sideline with the earth surface shape, and the low temperature light that this sideline branch sheds at first touches earth surface and temperature sharply descends, and at this moment paddy rice will be subjected to the influence of chilling injury.
The climate cloud amount of paddy rice head sprouting season increases, and general thick cloud layer weather lasts till the left and right sides time on the seven, and it's clearing up afterwards, and the key that can paddy rice be subjected to chilling injury depends on the weather and clears up the required time.Overcast to clear weather can avoid paddy rice to be subjected to the influence of chilling injury after the The sun came up, may be subjected to the influence of chilling injury before the The sun came up for fine weather paddy rice.In other words, reach and be not subjected to solar radiation about seven days and the ground of low-temperature condition is subjected to the influence of low temperature light again, paddy rice will be subjected to damaging to plants caused by sudden drop in temperature influence, and the spike of rice particle in autumn is failed the full loss that causes the underproduction.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of low temperature light that sunshine sideline branch sheds that intercepts, and prevents that paddy rice is subjected to the method for chilling injury.
For achieving the above object, the technical solution used in the present invention is: in paddy rice during head sprouting season, get hay or other incinerated matters around in the paddy field ready, after occur continuing many days cloudy weathers, when the paddy rice of clearing up before The sun came up will be subjected to influence dangerous of chilling injury, burn with hay or other incinerated matters around in the paddy field, burn smog and form artificial cloud layer, intercept the low temperature light that sunshine sideline branch sheds, will last till till the sun is launched high temperature light to get final product.After the The sun came up, the sunlight of irradiation will improve the temperature on ground on daytime, and paddy rice does not have the danger that is subjected to the chilling injury influence.
Adopt the present invention to prevent from can keep needed temperature in the growth process of riceplant after the paddy rice chilling injury method, the spike of rice full grains in autumn can guarantee stable yields or high yield.The technology of the present invention is easy to be easy-to-use, is convenient to promote.
Embodiment
Go out fringe during season in paddy rice, get hay around in the paddy field ready, as straw, corn stalk, after occur continuing many days cloudy weathers, overcast to clear before the The sun came up, when paddy rice will be subjected to chilling injury influence dangerous, the hay that some alkene has been got ready burns smog, the artificial cloud layer of overhead formation in the paddy field, intercept the low temperature light that sunshine sideline branch sheds, last till that always the sun launches till the high temperature light.
Claims (1)
1, a kind of method of preventing low-temperature cold damage of rice, it is characterized in that in paddy rice during head sprouting season, get hay or other incinerated matters around in the paddy field ready, after the cloudy weather that continues many days occurring, overcast to clear before the The sun came up, when paddy rice will be subjected to chilling injury danger, hay or other incinerated matters of having got ready burned, burn smog, make the sky, paddy field form artificial cloud layer with smog, intercept the low temperature light that sunshine sideline branch sheds, last till that always the sun launches till the high temperature light.
