一、试驗动机武汉气候的特点,即夏季的高热与潮湿及冬季的相对寒泠6——8月平均气温为27.9C冬季絕对低温—9。C——-10。C甚至到—16。C以下的(1954——1955冬)全年雨量1266mm中多集中在4—7月其总和为934.9mm,根据一般文獻記載苹果裁培夏季平均温度(6——8月)不能超过20。C,所以很多人認为武汉一帶裁培果是不适宜的,又由于冬季寒冷,柑桔类也不能种植,这样不利的自然条件,纔形成了武汉缺果的原因,解放以后学习了米邱林学說知道用种籽馴化的方法把南方怕寒的果树越过了它們和裁培界限用改变生活条件方法去改变它們的遺傳性,是否我們能够用同样的理論把北方果
First, the experimental motivation Wuhan climate characteristics, namely the summer heat and humidity and the relative cold in winter 6 - August average temperature of 27.9C in winter absolute low temperature -9. C --- 10. C even to -16. C (1954-1955 winter) annual rainfall of 1266mm is mostly concentrated in April-July, the sum of which is 934.9mm. According to the general literature, the summer average temperature of apples cutting (June-August) can not exceed 20%. C, so many people think that the area around Wuhan is not suitable for cutting pears, and because of the cold winter, citrus can not be planted. Such unfavorable natural conditions formed the reason for the lack of fruit in Wuhan. After the liberation, The forestry doctrine says that using the method of seed domestication, the southern frigid fruit trees crossed their boundaries with the cuttings and the living conditions to change their heredity. Can we use the same theory to treat the northern fruit
