去年下半年,我们对部分父、母本花期不迂的汕优二号制种田,进行了喷花粉试验。试验结果,喷两次花粉的母本亩产种子8.8斤,而未喷花粉的母本亩产只有3.56斤.可见在父、母本花期不迂或相迂不良的情形下,喷花粉是一种行之有效的补救措施,它可变母本无收为有收,少收为多收,而且方法简单,花工少,成本低。具体作法是:事先准备好一只干净的喷粉器;再用一只脸

In the second half of last year, we conducted pollination tests on some Shanyou No.2 farming systems, in which some parents and mother flowers were not inflorescences. Test results, spray twice the pollen mother per mu yield of 8.8 kg of seed, but did not pollen mother per mu yield of only 3.56 kg. Can be seen in the parent and the female flowering not phase or bad phase, the pollen is a Kind of effective remedial measures, it has variable income for the income collection, less income for more income, and the method is simple, less labor, low cost. The specific approach is: prepared in advance a clean duster; use a face again
