Abstract

Abstract:

In order to solve the problem of the reduction of the migration of young rural labor force and the aging of the population,the enthusiasm for food crop production has been greatly reduced,and it is urgent to explore rice planting methods with less labor input and matching high-yield varieties.Through field trials from 2017 to 2019,two common and easy-to-promote planting methods were compared,and 14 early rice varieties and 12 late rice varieties were screened for easy purchase.The planting methods were simulated machine transplanting and machine direct seeding.Effects of different planting methods on the growth period,yield and dry matter weight of different early and late rice varieties.The results showed that direct seeding could shorten the growth period compared with transplanting.The average growth period of early rice direct seeding was shortened by 7 d compared with transplanting,and the average growth period of late rice was shortened by 8 d.The growth period of direct seeding had a smaller fluctuation range and more stable performance than transplanting.The annual average yield was significantly higher than that of transplanting,which was 29.71% higher in 2017,12.37% higher in 2018,and 7.15% higher in 2019,and it was found that the yield and dry matter accumulation at different periods were affected by the variety,the planting method and year had a very significant effect;through the linear regression covariance test,there was a positive correlation between the yield and the dry matter accumulation,which showed that the yield increases with the increase of the dry matter accumulation,and the coefficient of determination of the linear regression of the direct seeding method(R²)were higher than the transplanting method.A comprehensive comparison showed that the direct seeding method performs better in both the early and late rice planting methods,and the stable and high-yield(high-yield performance in the field in three years)that is matched with the direct seeding method is screened.The early rice variety Zhuliangyou 829(the yield fluctuation range of 6.02—10.90 t/ha),Yuliangyou 4156(6.49—10.22 t/ha),and stable and high-yielding late rice variety Wuyou 308(10.43—12.65 t/ha),the selected early and late rice varieties had moderate growth periods and can be effectively connected achieve high-yield planting of early and late rice.
