Popularization of double-late wheat technology

The so-called "double night" is the timely late harvest of summer crops and the timely late sowing of winter wheat. With the global warming and the backward movement of the high temperature period, a new subject has been put forward for the reform and adjustment of the farming system in China. After several years of research, it is found that the timely late harvest of summer crops and the timely late sowing of winter wheat are the direction of the reform of our farming system.

1. Summer crops are harvested late at the right time.

Taking summer corn as an example, timely late harvest can improve the utilization of light and heat resources and increase grain weight, which is an effective measure to increase unit yield. The practice shows that the yield of summer corn can be increased by about 10 kg per mu by one day's late harvest and by 40-50kg by one week's late harvest. Therefore, it is advocated that corn should not be harvested in September and rush to harvest and seed in October. The same is true of cotton, timely late harvest, can increase the pre-frost flowering rate, is one of the effective measures for cotton to obtain high yield.

2. Winter wheat is sown late at the right time.

According to the actual situation in recent years, the timely and late sowing of winter wheat is beneficial to the steady growth and safe overwintering before winter. As the saying goes, "there is no prosperity of wheat", "wheat is afraid of 'big ears'." That's the truth. Thus it can be seen that the popularization of "double night" technology is the reform of agricultural farming system, and it will be applied as a template technology for autumn harvest and autumn planting.
