夏谷具有播期晚、生育期短、生长快、秆矮、穗小、根少的生育特点。为此,管理应以突出“早”字,以期达到壮苗、壮根、壮秆、壮穗,为夏谷丰产打下基础。 一、早抢播,促苗全、苗壮、高产。 夏谷应适墒下种,发芽时需吸收自身重量25％～30％的水份,土壤最低含水量 Summer Valley has a sowing date, short growth period, fast growth, short stalk, spike, root less reproductive characteristics. To this end, management should be to highlight the “early” word, in order to achieve strong seedlings, strong roots, strong stalks, Zhuang spike, lay the foundation for summer grain yield. First, early snatch broadcast, promote seedling full, Miao Zhuang, high yield. Summer Valley should be appropriate under the kind of moisture, germination need to absorb its own weight of 25% to 30% of the water, the lowest soil moisture
