小麦开花后籽粒开始发育,这是增重的关键时期,大有潜力可挖。据1977—1982年六年测定,我县小麦千粒重平均在28—37克之间,相差9克,千粒重是低而不稳的。就我县六年中平均产量水平来说,千粒重增加1克,每亩可增产7.7斤;千粒重如增加3—5克,可增产23—39.4斤。在高产地块增减产幅度更为明显。然而人们往往认为这一时期大局已定或丰收在望了,便产生盲目乐观而放松管理,结果把即将到手的粮食丟掉了,给生产带来了一定的损失。
After the flowering of wheat grains began to develop, which is a critical period of weight gain, great potential to dig. According to the determination of 1977-1982 six years, the average grain weight of wheat in our county is between 28-37 grams, a difference of 9 grams, the grain weight is low and unstable. In my county average output level in six years, the 1000-grain weight increase of 1 grams per mu yield 7.7 kg; 1000 grain weight as increased 3-5 grams, yield 23-39.4 kg. In high-yielding land increase and decrease of more significant rate. However, people often think that during the period when the overall situation has been set or the harvest is on the horizon, they will be blindly optimistic and relaxed in management. As a result, the forthcoming grain will be discarded, resulting in some loss to production.
