一、谷子不同发育阶段的需水规律谷子不同发育阶段对水分的要求是不同的(图1)。一般来讲,谷子对水分的要求,从播种到出苗阶段是“喜墒怕旱”。谷子发芽不仅需要一定的温度,而且需要一定的水分(一般是田间含水量的10—20%)。即使地里水分充足,但坷垃较多,在气候干燥、多风的情况下,也难保证安全出苗。因此,播种前精细整地,播后认真镇医,是保证安全出苗的重要措施之一。从出苗到拔节阶段是
First, the water requirements of different developmental stages of millet Millet requirements of different development stages of water is different (Figure 1). In general, millet moisture requirements, from sowing to the emergence stage is “hi moisture fear drought.” Millet germination not only requires a certain temperature, but also requires some water (usually 10-20% of the field moisture content). Even though there is sufficient water in the ground, there are more bugs in the ground and it is difficult to ensure safe emergence even under dry and windy conditions. Therefore, fine sowing before sowing, after sowing a serious town doctor, is one of the important measures to ensure safe emergence. From emergence to join stage is
