近年来,农业生产广泛应用塑料薄膜覆盖地面,这是现代农业生产较为有效的一项新技术。我市为解决由于积温不足,造成繁殖“两杂”亲本种子熟期偏晚、成熟度差、水分大、芽率低等问题,于1982年搞了“两杂”亲本繁殖田地膜覆盖试验,获得了早熟、高产、增收的明显效果。试验全市共有三处“两杂”亲本繁殖地膜覆盖对比试验田。为了便于对比,对照区的铲趟管理与大田相同,其它都与地膜覆盖同等条件。其中,太平山一队“冬黄”繁殖田地膜覆盖对比试验面积1.7亩,春翻春起垅,行距50厘米,株距30厘
In recent years, extensive use of agricultural plastic film covering the ground, which is more effective modern agricultural production of a new technology. In order to solve the problem of lack of accumulated temperature, resulting in the problems such as late maturity, poor maturity, large water content and low bud rate of the breeding “two hybrids” parent seeds, the city engaged in “two hybrids” parental breeding fields in 1982 Membrane coverage test, access to early maturity, high yield, the obvious effect of income. A total of three trials in the city “two hybrid ” breeding plots to cover the field of comparative experiment. In order to facilitate comparison, control area shovel management and field the same, and others are the same conditions with the mulching. Among them, the Taipingshan team “winter yellow ” breeding field film covering area of 1.7 acres of contrast test, spring turning spring 垅, spacing 50 cm, spacing 30%
