在杏园上建造大棚,对杏树大棚栽培中需要解决的主要问题进行了试验研究。结果表明:杏树一般在12月底结束休眠(需低温量860小时左右),1月上旬扣棚较为适宜。棚内平均气温花期控制在11℃~13℃,夜间不低于6℃,果实第1速生期13℃~18℃,夜间不低于7℃,硬核期18℃~22℃,夜间不低于10℃;第2速生期22℃~25℃,夜间不低于15℃。采用蜜蜂传粉和人工授粉座果率可达36.31%和35.4%;幼果膨大期,喷施0.1%硼酸,硬核期喷100×106B9均可明显提高座果率。
In the apricot garden construction of greenhouses, cultivation of almond trees in the cultivation of the main problems to be studied. The results showed that apricot usually ended dormancy at the end of December (about 860 hours of low temperature needed), and the shedding in early January was more suitable. The average greenhouse flowering period is controlled at 11 ℃ ~ 13 ℃, at night not less than 6 ℃, the first fast-growing fruit 13 ℃ ~ 18 ℃, at night not less than 7 ℃, hard core 18 ℃ ~ 22 ℃, not low at night At 10 ℃; the second fast-growing period 22 ℃ ~ 25 ℃, at night not less than 15 ℃. The results showed that the rate of fruit set was 36.31% and 35.4% with bee pollination and artificial pollination, respectively. When young fruit was swollen, 0.1% boric acid and 100 × 106B9 .
