Abstract

Abstract:

In order to explore the effect of sowing date on daily yield of mechanical indica hybrid rice under different ecological conditions and put forward the corresponding countermeasures, for high yield, a two-factor split plot design, with three indica hybrid rice (Yixiangyou 2115, F you 498, and Chuanyou 6203) and four sowing dates, was conducted to study the effects of different sowing date and ecological conditions on the whole growth period, grain yield and daily yield of machine-transplanted rice in Nanbu, Shehong, Anzhou, and Dayi of Sichuan province. The results showed that there were differences in the whole growth period, yield and daily yield of rice under different ecological conditions. As the sowing date was postponed from late March to early May, the days from sowing to jointing were shortened and the days from heading to maturity were increased, the average whole growth period was shortened from 159.5 days to 150.7 days, the average yield was decreased from 10,260.45 kg hm ^-2 to 7795.83 kg hm^-2, and the average daily yield was decreased from 64.58 kg hm^-2 d^-1 to 51.95 kg hm^-2 d^-1. The effects of meteorological factors on grain yield and daily yield of machine-transplanted indica hybrid rice were different under different ecological conditions. The yield was significantly positively correlated with the average daily temperature range and sunshine hours of the whole growth period, while yield was significantly negatively correlated with the average daily temperature, average daily minimum temperature, average daily relative humidity and rainfall of the whole growth period of rice. The daily yield was significantly positively correlated with the average daily temperature range and sunshine hours of the whole growth period, while significantly negatively correlated with the average daily minimum temperature and the average daily relative humidity of the whole growth period. For different experimental region, the daily yield was significantly negatively correlated with the average daily temperature in Nanbu, Shehong, and Dayi. In the west plain area and the middle and northeast hilly areas of Sichuan Basin, the preferred varieties should be F you 498, winter idle field or vegetable stubble rice should be sown in late march, while wheat (rapeseed) stubble rice should be sown as early as possible after the previous harvest, and generally sown in late April for higher yield and daily yield.

Key words: rice, sowing date, mechanical transplanting, daily yield, ecological conditions
