一为什么要建立留种地据1953年我们在各地调查,农家小麦品种一般极为混杂,在旱地尤其厉害。例如临汾田村胡玉堂地杂有四个品种,洪洞辛庄全部麦地都混杂一半以上。有不少农民自己不留种,临种时到各处去张罗;有的同粮食堆在一起。结果发芽不好,病虫害多,再加品质不齐,成熟期不一致,造成产量上很大损失。 First, why should we establish a reserve? According to our survey in various places in 1953, the variety of farm wheat is generally very mixed and especially notable in drylands. For example, Linfen Tamura Hu Yutang miscellaneous miscellaneous four varieties, all of Hongtong Xinzhuang are mixed more than half of the wheat fields. Many peasants do not keep their own species, and when they come to Tibet, they go everywhere; some pile up with the grain. The results of poor germination, pests and diseases, coupled with poor quality, maturity is inconsistent, resulting in a great loss of production.
