水分是菜豆生长发育很重要的环境条件之一,但若浇水不当又很容易产生茎叶生长和开花结果间争夺养分的矛盾而招致落花落荚,降低产量。苗期以营养生长为主,宜控制水分,中耕2—3次,提高地温,使幼根早发旺长,为以后的开花结荚奠定良好基础。定植苗过3—4天后轻浇一次缓亩水,然后中耕细锄。初开花期不浇水,这时供水多,植株营养生长过旺,消耗养分多,
Water is one of the most important environmental conditions for the growth and development of kidney beans. However, if the watering is inappropriate, it is very easy to produce the conflict between the growth of the stems and leaves and the blooming of fruits, which will result in falling pods and reducing the yield. Seedling to vegetative growth-based, should control the water, cultivated 2-3 times, increase the ground temperature, so that young root early flourishing for the future flowering pod lay a good foundation. 3-4 days after planting seedlings lightly poured once a mu of water, and then cultivated fine hoe. Not flowering at the beginning of flowering, then water supply, vegetative growth over-plant, consume more nutrients,
