The application of "no deep plowing" soil conditioner will increase the permeability of the soil, promote the growth and development of rice roots and increase the utilization of rice for fertilizers, thereby increasing rice yield. On this basis, we must pay close attention to the following measures and have a significant effect on rice production.
1. Increase the number of panicles.
1 nurture strong and strong. Provide a good foundation for early delivery and early delivery.
2 reasonable dense planting. According to the planned number of harvested panicles and the estimation of tillers after planting, the number of basic seedlings was inserted (thrown).
3 promote low birth early delivery, control high birthing less hair. Promote low-position early-onset, insert enough seedlings in time to expose fields, dry fields, control of high-section of the invalid childbirth, so that nutrients concentrated in the effective delivery of early-onset, to improve the rate of tillers into the panicle.
2. Increase the number of grains per spike.
1 Promote the thick stems before the differentiation of young panicles. On the basis of the strong and prosperous, we must ensure that the rice plants have the necessary supply of nutrients for the stable growth of the rice stalks during the delivery period in Datian, so that the rice stems are thick and the branches of the rice stems are strong, making the big ear a good foundation.
2 Supply young spikes with sufficient nutrients for differentiation. Usually at the beginning of young panicle differentiation, if the leaf color is light, it is necessary to apply “promoting flower fertilizer†to promote differentiation to form more spikelets. In the mid-stage of young panicle differentiation and development (about 20 days before heading), if the leaf color is lighter, “Plastic Fertilizer†should be applied to reduce the degradation of spikelets and improve the fertility rate of spikelets.
3 Adjust the temperature with water and increase the seed-setting rate. In case of dry and cold weather during the heading and flowering period (such as cold dew), the water can be immersed and moisturized to increase the temperature, reduce the damage of low temperature and dryness to rice, and increase the seed setting rate.
4 Increase dry matter accumulation before heading. Before heading, pay attention to the nutrient supply needed for growth, but do not overgrow the growth and allow the photosynthetic product to accumulate to ensure that more material is transferred to the grain after heading and increase the seed setting rate.
3. Increase the grain weight.
1 to ensure that the late panicle development has good nutritional conditions, so that the chaff grow larger, it will accommodate more grouting material.
(2) Wet irrigation during the mature stage of grouting, and the roots should be maintained to form more photosynthetic products, so that the grain filling degree is good.
3 In the growth period of rice, combined application of "Shufeng 481" plant growth regulators will help promote the formation and growth of leaves, increase the photosynthetic capacity, promote the speed of grain filling, increase grain weight gain, and increase grain protein and nitrogen-based acid. Content, improve quality, shorten growth period, promote grain maturity, and gain valuable time for planting double-season rice.
