How to Scientifically Choose Rice Varieties for Planting
How to scientifically choose rice varieties for planting should follow these principles: (1) Certified varieties with strong resistance. (2) In the same village or town, large-scale planting of a single variety should be avoided; 3-4 varieties should be mainly promoted and planted in combination. (3) Since this year's climatic conditions are not very favorable, varieties with a slightly earlier maturity period should be chosen. (4) Choose varieties sold by legitimate manufacturers. It is best to buy seeds from the breeding unit, because the breeding unit understands the characteristics of the varieties and the suitable regions. The seed purity is relatively good,
