多年的生产实践证明:理想的窝瓜种应该是一两多重,四指来长,尖嘴大腚,健壮无病。使用这样的小瓜种,不仅用种少,成本低,而且生活能力强,对保全苗、创高产起着重要的作用。但是前些年,窝瓜用种一直是在麦茬地瓜大田里选留,劳力用的不少,一亩大田选不出一亩窝瓜的用种,结果是数量选不足,质量又不好,不仅年年完不成种植计划,而且烂母缺苗较重,影响了产量的进一步提高。 Years of production practice has proved that: the ideal nest watermelon species should be more than one or two, four fingers to the long, sharp-eyed big bream, robust disease-free. Use of such a small melon species, not only with less species, low cost, but also strong ability to live, to save seedlings, a high yield plays an important role. However, a few years ago, the use of Wogua species has been selected in the field of wheat stubble sweet potatoes, labor with a lot of acres of fields can not choose an acre nest melon species, the result is the lack of quantitative selection, the quality is not good, Not only does the program not be completed by the end of each year, but the heavy seedlings of rotten nursery stock affect the further improvement of output.
