1.栽稀长密,充分利用光能水稻分蘖能力很强,条件适宜时穴分蘖数可超过100株。但不少稻农却习惯于以密植的方法达到理想的亩株数,这样既浪费了秧苗和水肥,又降低了光能利用率。采用壮秧稀植后,利用壮秧具有较强的生理活性和返青快、分蘖快又多的特点,依靠分蘖的逐渐长大和繁生,达到个体和群体分布合理和协调,可充分利用光能,为丰产打下基础。
1. Cultivated dilute long, make full use of light Rice has strong tillering ability, suitable conditions for the number of tillering points can be more than 100. However, many rice farmers are accustomed to achieving the ideal mu number of plants by close planting, thus wasting seedlings, water and fertilizer and reducing the utilization of light energy. The use of strong sprouts seedlings, the use of strong seedling has strong physiological activity and fast green, tiller faster and more features, relying on the gradual growth and growth of tillers to achieve the distribution of individuals and groups reasonable and coordinated, can make full use of light energy, Lay the foundation for high yield.
