The growth of early rice Honda is in the season when the temperature gradually rises from low to high, and the growth period of Honda is generally 80 to 90 days (only 60 to 70 days for early maturing varieties or early rice with the third crop). From the point of view of growth rate, the overall performance is slow in early birth and faster in later period. As early rice vegetative growth overlaps with reproductive growth, there is only one peak of absorption and short and long duration, while the early rice yield depends on a certain amount of effective panicles. Therefore, early rice requires early-onset panicle blasting after transplanting.
Generally, the double-cropping early-season rice reached its tillering peak 15 to 20 days after transplanting, and the three-cropping early-season rice reached the tillering peak two weeks after transplanting for high yield. For the fertility characteristics of early rice, adopting the corresponding fertilization technology is to apply enough basic fertilizer and apply top dressing early to coordinate the contradiction between early rice need fertilizer and soil fertilizer supply. The specific fertilization technology is that all organic fertilizers, phosphorus, potash fertilizers, and 80% chemical nitrogen fertilizers are applied as full-scale base fertilizers, tiller fertilizers are applied 5 to 7 days after transplanting, and panicle fertilizers are often used for seedlings, and most regions do not Spike fertilizer.
For some early rice varieties with long growing period or high fertility rice fields, the method of fertilization before stable attack is often adopted, that is, under the premise of inserting the basic seedlings, the stability is long in the early stage, no more tillers are required, and sufficient panicles are ensured by the basic seedlings. Through the attack, it has achieved many grains, full grain, and high yields. The proportion of fertilizer is 30% in the previous period, 50% in the middle period, and 20% in the latter period. Early-season rice can be harvested with high-yield fertilizer by using one-head fertilization method and staged fertilization method. All regions should adopt local conditions based on soil, rice varieties, climate, irrigation, and fertilizer.
