Problems solved by technology

Spraying paraquat before the rice is harvested, the drug will remain on the rice grains, which is not conducive to the safety of human and livestock consumption
At present, there is another method, using diquat one week before rice harvest to dry the stems, leaves and seeds. However, diquat may cause a certain reduction in yield, so it is only suitable for harvesting in the rainy season

Effect test

Embodiment 1

[0023] Comparative example one, use ethephon alone.

Embodiment 2

[0024] Comparative example two, use gibberellin alone.

[0025] The compositions of the above-mentioned comparative examples and the comparative examples are respectively a large group, and each large group is divided into three experimental groups of seven-day group, ten-day group and fifteen-day group, and each experimental group is based on 200 per mu. Milliliter composition and water 40 kg consumption, the seven-day group was sprayed seven days before the harvest of rice wax ripening period, the ten-day group was sprayed ten days before the rice wax ripening period harvested, and the fifteen-day group was sprayed at the rice wax ripening period Spraying was carried out 15 days before harvest, and the withering rate and grain water content were measured and compared after each group completed the test. The data are as follows:

[0026]

[0027] From the comparative experimental data, it can be seen that the effect of accelerating the withering of the seven-day group is b...

Abstract

The invention discloses a composition for rice withering acceleration. The composition comprises diquat and a growth regulator; the diquat and the growth regulator are prepared according to a weight ratio of (1:1) to (10:1). According to the composition for rice withering acceleration, the diquat and the growth regulator are blended, therefore not only is the problem that production reduction after withering acceleration is caused by the diquat solved but also the problem of rice dewatering caused by withering acceleration can be solved; airing labor cost is reduced, and economic benefit is effectively increased.

Description

technical field [0001] The invention relates to a rice withering-reducing composition. Background technique [0002] Rice is the main food crop in my country, with a large planting area and its output ranks first in the world. The main rice producing areas in my country are mainly the Northeast region, the Yangtze River Basin, and the Pearl River Basin. However, with the reduction of land area and the increase of labor costs, the number of sun-drying sites has been severely reduced, especially in the Yangtze River and Pearl River basins. The early rice harvest period has more rain, which is likely to cause moldy grains. [0003] The method of chemically accelerating the dehydration of rice can meet the needs of mechanized harvesting and reduce harvesting losses. It can not only promote consistent grain ripening, improve yield and quality, but also reduce the load of mechanical harvesting. Therefore, the application range of chemical ripening in crops has become wider and w...
