利用矮生菜豆品种,于秋季露地播种,适时用小拱棚保护可延迟采收。 一、选用对路品种。秋延栽培宜选用适应性强。较耐热耐寒、早熟丰产的品种,如法国芸豆、美国供给者等。 二、整地。8月中旬前茬腾地后,亩施5000公斤腐熟有机肥作底肥,深耕耙平。根据所用薄膜的幅宽确定畦宽,一般薄膜宽为畦面宽的1.6倍。 三、适期播种。播种过早,结荚期提前,达不到延迟供应的目的;过晚则因气温低,不易形成高
Use of dwarf beans varieties, open seeding in the fall, timely protection with a small shed can delay the harvest. First, choose the right species. Autumn planting should be used to adapt adaptability. More resistant to heat and cold, early maturing varieties, such as French kidney beans, the United States suppliers and so on. Second, soil preparation. Before the middle of August Tang Teng, Mushi 5000 kilograms of decomposing organic fertilizer as base fertilizer, deep rake flat. According to the width of the film used to determine the width, the general width of the film is 1.6 times wide noodles. Third, the appropriate sowing. Sowing too early, pod stage ahead of schedule, reach the purpose of delayed supply; too late because of low temperature, not easy to form high
