P_2西瓜是杂交一代种。通过近几年的小区试验及较大面积示范推广,表现具有明显的杂种优势:产量高,一般亩产6000—7000斤,最高可达万余斤;生长势旺盛,抗逆力强,后期不易倒秧,因此头瓜收获后,可留二茬瓜,每亩还可增收二千余斤;品质好、味甜、汁多、肉细、籽少,含糖量10—13％,中、边糖梯度小;单瓜平均重8—10斤,最大瓜重20余斤;熟性早,生育期100—110天,在兰州地区4月初播种,7月上、中旬上市;适应性强,目前在省内外已推广千余亩,在甘肃省的大部分地区以及黑龙江、河北、安徽、陕西等部分地区都已试种成功,深受生产者和消费者的欢迎。1984年在全国西瓜品种评比中P_2名列早熟杂交种的第一名。
P_2 Watermelon is a hybrid generation. Through the trial of plots in recent years and demonstration and popularization of large area, the performance has obvious heterosis: high output, generally 6000-7000 kg per mu and up to 10000 kg; strong growth potential, strong resistance and not difficult in later period Inverted transplanting, so the head melon harvest, you can stay two crop melon, but also increase the yield per acre more than two thousand jin; good quality, sweet, juicy, thin meat, seeds, sugar content of 10-13% The sugar gradient is small; the average weight of single melon is 8-10 kg, the maximum weight of melon is more than 20 kg; the maturity is early and the growth period is 100-110 days; the seed is sowed in early April in Lanzhou region and the market is listed in mid- At present, more than 1,000 mu have been popularized in both inside and outside the province, and have been successfully planted in most areas of Gansu Province as well as parts of Heilongjiang, Hebei, Anhui and Shaanxi, and are well received by producers and consumers.
