二、井水温度低,漏水漏肥新开稻田如不彻底进行精细耙地,往往漏水严重,导致漏水漏肥.为保持水层,就得增加灌水次数,而井水温度低(只有9℃),势必降低土壤温度,使秧苗滞长,影响水稻全年的生育,造成贪青晚熟而减产.这样的地块要在插秧前结合整平土地,多次精细耙地,使犁底形成一个粘土层,土粒堵塞孔隙,不但能提高土壤温度,也叫防止漏
Second, the well water temperature is low, leaking leaky If the newly opened rice paddies do not thoroughly fine rake, often leaking serious, leading to leakage of water and fertilizer to maintain the water layer, you have to increase the frequency of irrigation, and well water temperature is low (only 9 ℃ ), Will inevitably reduce the soil temperature, so that the seedling stagfalong, affecting rice year-round fertility, resulting in late-blooming and cut green .This plots in front of transplanting combined with leveling the land, repeatedly fine rake, the plowshare to form a Clay layer, soil particles plug the pores, not only can improve soil temperature, also known as prevent leakage
