硼、锌、钼、锰、铁、铜是果树生长必需的六种微量元素。别看它的用量极少,但它对促进果树生长发育的作用却大得出奇。 硼在果树体的含量只有百万分之十几,但它却能大大影响果树生殖器官的发育,缺少了硼,花的发育不良,或不能正常形成,妨碍受精,就会出现“花而无实”。为补充硼的不足,果农常常采用根外施硼的办法。 钼在果树体中,占不到百万分之
Boron, zinc, molybdenum, manganese, iron and copper are the six trace elements necessary for the growth of fruit trees. Do not look at its use of very small, but its role in promoting the growth and development of fruit trees is surprisingly surprising. Boron in the fruit tree body content of only a few ten millionths, but it can greatly affect the fruit tree reproductive organs development, the lack of boron, flower dysplasia, or can not be formed, impede fertilization, there will be “flower without real”. To supplement the lack of boron, fruit growers often use the method of applying boron to the roots. Molybdenum in fruit trees, accounting for less than one millionth
