To do a good job of throwing plastic floppy disks, we must do a good job of the following: First, we must control the temperature inside the film. The temperature in the film is controlled at about 30°C. When the weather is fine at noon, the temperature is high. If the temperature is higher than 35°C, the two ends of the film should be uncovered at the same time. Burn seedlings".
The second is to manage the water. Timely dredge the ditch, before the emergence of the disk (bed) soil moist, no drought after emergence, no watering; pouring film when pouring enough water; seedlings water can not be on the surface during the whole period.
The third is to give a good "send marriage fat" and lay "send martial medicine." 2~3 days before throwing planting, “send marrying manure†will be treated with 3 grams of urea and 3 grams of potassium chloride per plate, and 300 grams of water will be poured. Each per acre field can be used for 50 grams of meal and 100 milliliters of water. 45 kg of water, even spray, to prevent the early rice Daejeon stage of leafhopper and a generation of II.
