After sowing seedlings in rice fields, they will enter the management period of Putian. It is necessary to focus on the management of fertilizer and water and the prevention and control of pests and diseases. In particular, there are differences in the management measures of fertilizer and water in different ways of raising and breeding.
The scientific tube water bed is dry and the soil is kept moist before the 3 leaf stage, and the water is strictly controlled after the 3 leaf stage. When the seedlings are rolled at noon and can be watered in the evening, they can not be watered, but the leaves can not be stretched and shed before the evening. The water should be replenished in the morning of the next day (not to pour cold water at noon), to achieve control and promote the development of roots. Short and strong dry seedlings. Machine inserting 秧 秧 秧 ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( Packing; 2 to 3 leaf stage depending on the weather conditions, diligently smashing the horse water, so that the front water is not connected to the water; 3 to 4 days before transplanting, the half ditch water seedlings are poured to facilitate the machine insertion. Plastic tray throwing 秧 秧 秧 至 至 至 至 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 It was not fully deployed in the morning to replenish water. In the late stage of Putian, in case of continuous rainy weather, it is necessary to drain and reduce the water in time to prevent the fertilizer and water from colliding with the seedlings; in case of continuous drought, the water should be poured and watered one day before the transplanting (not suitable for irrigation, otherwise it is difficult to start the plate and easy to damage) Disk), so as not to loosely affect the throwing of the root ball. Routinely moisturizing the valley to the 1 leaf 1 heart period, to achieve sunny full ditch water, cloudy and semi-ditch water, dry water on rainy days, keep the seesaw wet. The water layer is established in the 3 leaf stage, and shallow water irrigation is carried out to promote tiller growth. For micro-sprinkler irrigation, water is sprayed once before and after 10 o'clock in the morning and around 4 o'clock in the afternoon. According to the needs of planting age, the water spray time is scientifically determined.
Applying fertilizer timely and appropriate fat dry nursery bed 1 leaf stage application "weaning" fat, urea per acre with 7.5 to 10 kg; length 3 leaf stage application crude fat, about 7.5 kg of urea per acre with, as appropriate, after the 4 leaf stage Filling the fertilizer. Each fertilization must be added with water to form a fertilizer solution of about 1% evenly, to prevent fertilizer from burning. The use of Zhuangzi nutrient for the transplanting of oysters generally does not require topdressing, but when the seedlings are lighter in the 1st and 1st heart stage, the urea can be applied 4 to 4.5 kg per mu, and thin water is formed in the evening when the seedling leaves are spouted. Apply evenly after the layer or add 1,000 kg of water. Plastic tray throwing oysters 1 leaf 1 heart period and 2 to 3 days before creping, after the establishment of the water layer, respectively, 4 to 5 kg of urea per acre. Conventional wet nursery should be applied early to "weaning" fertilizer, see Miao Qiao apply relay fertilizer, re-apply body fat. "Weaning" fertilizer applies 5-6 kg of urea per acre in 1 leaf 1 heart period, and 3-5 kg ​​of urea per acre in the 3~4 leaf stage, and the fertilizer is applied per mu for 2 to 3 days before drawing. 8 to 10 kg.
Timely prevention and control of diseases, pests and weeds should focus on the prevention and control of pests and diseases of the first generation of Putian, such as Laodelphax striatellus, aphids, seedlings, rice blast, and rice locusts.
