改善植物前期发育阶段的营养条件,是保証良好和快速出苗的重要因素之一。早而良好的出苗能较早的开始光合作用,改善單独利用种子中貯藏物質营养,而为用根系吸收空气中养料,以弥补植物幼小时期之营养不足;低速的发芽使出苗緩慢而不良,大粒种子播种时因营养物質之不足,將白白地消耗了貯藏的养料。在这一时期因营养物質的不足不仅使生長落后,而且將影响到植物的整个营养时期。所以說,具有快速发芽的种子是丰收的前提条件之一。播种期浸种并在阳光下晒干是提进发芽最有效的方法。莫斯科季米里亚捷夫农学院农学系(契尔诺瑪玆付教授)试驗,冬小麦种子水浸后并在
To improve the vegetative conditions during the early stages of plant development is one of the important factors to ensure good and rapid emergence. Early and good emergence of early start of photosynthesis and improve the utilization of seed in the separate storage of nutrients, but to use the roots to absorb nutrients in the air to make up for the nutritional deficiencies of young plants; low-speed sprouting so that the emergence of slow and poor, Large seeds sown due to lack of nutrients, will be consumed in vain nourishment. During this period not only the lack of nutrients not only make the growth lag, but also affect the entire vegetative period of the plant. So, having a rapidly germinating seed is one of the prerequisites for good harvest. Seed soaking and soaking in the sun is the most effective way to promote germination. After a series of experiments with the Department of Agronomy, Gijljakov Academy of Agricultural Sciences in Moscow (Professor Chernomaz), the winter wheat seeds were flooded
