通过调查防问,对奎屯地区的冬菜播种,提出以下两点意见:一、播种期播种早晚,由于气候条件不同,影响冬菜的出苗和生长.1.胡萝卜:一九六五年出苗不齐.通过不同播期的气候条件分析,六月中旬至七月上旬播种的胡萝卜,保苗率与幼苗出土前后5天(即播后7—11天)地表最高温度有密切关系.胡萝卜的保苗率随地表最高温度的增高而降低.六月下旬以后播种的胡萝卜,在出苗以后,因高温危害而枯死.要避免高温威胁,应在六月上旬播种.
Through the investigation of prevention and control, we planted the winter vegetables in the Kuitun area and put forward the following two opinions: First, the sowing date sowing sooner or later, due to different climatic conditions affect the emergence and growth of winter vegetables .1 carrot: 1965 emergence of missing. According to the climatic conditions of different sowing date, the seedling protection rate of carrot planted in mid-June to early July is closely related to the maximum surface temperature of the ground five days before and after emergence (7-11 days after sowing) Highest temperature increases and decreases.After the end of June carrots sowing, after emergence, due to high temperature damage and death.It should be to avoid high temperature threats, should be sowed in early June.
