谷子和野生植物不同,不具有生物的自然稀疏特性。但生产上为了要保证苗全满垄,所以总要播种较实际留苗密度大数倍的种子。如以晉东南大部地区每亩播种一斤半种籽计,约有二十六万多粒种子,播入土中后,假如按出苗率七成计算,每亩至少可以长出十八万株苗。谷子在苗期是喜疏怕稠,稠了个体间势必出现争肥、争水、争光的矛盾,其结果常会形成荒 Unlike wild plants, millet does not have the biological natural sparse properties. However, in order to ensure the production of seedlings full ridge, so always planted seedlings density than the actual number of seedlings several times. For example, in most areas of southeastern China, sowing about half a kilo of seed per acre per mu, about 260,000 seeds are planted, seedling. Millet in the seedling is hi like fear of thick, thick individuals are bound to appear fat, water, glory of the contradiction, the result will often form a waste
