What is the best variety for direct seeding of rice?

In order to know the best variety of direct seeding rice, we must master the following questions: 1. What is direct seeding rice? Second, what are the characteristics of rice direct seeding? Third, the selection principle of rice varieties. 1. Direct seeding of rice refers to a planting method in which rice seeds are directly sown or spread in the field without raising seedlings. 2. Characteristics of direct seeding of rice: Advantages: (1) Labor saving. Direct seeding rice does not need seedling raising and transplanting, which reduces the use of transplanting tools and saves seedling fields. (2) It is beneficial to low tillering and more effective panicles. (3) The growth period is shortened, there is no need to pull out seedlings and transplant them, there is no turning green period, and the growth period is fast, generally maturing about 5 days before transplanting. Disadvantages: (4) It is difficult to complete the seedling. Because of the cold weather in direct seeding fields, especially early rice, the germination rate is not high, and it is also endangered by birds, such as sparrows. (5) Grass is harmful. Because the seeds of direct seeding rice germinate in the field, there should not be too much water on the field, so it is advisable to leave the field wet, rice seeds grow and weeds grow. (6) easy to lodging. Direct seeding seeds are uneven, dense and prone to lodging. 3. Selection principle of rice varieties: The selection of rice varieties should not be the same, but should be adapted to local conditions, different places, different varieties and different varieties of early rice and late rice. The general principle is: it is best to choose early and middle-maturing varieties with good cold tolerance at seedling stage, early growth, rapid development, moderate tillering ability, strong body and short body, strong disease resistance and lodging resistance.
