薄膜地面复盖栽培技术,是现代瓜菜生产的一项早熟、高产的技术措施。在国外如日本、意大利、法国、美国等工业发达国家已经在生产中应用。目前日本在西瓜、甜瓜保护地栽培及露地栽培中,几乎全部实现薄膜地面复盖栽培化。起到了省工、省肥、省水的作用,达到了早熟、优质、高产的目的。我国从1979年开始,在东北,华北,西北三个地区,在蔬菜上开展该项科学研究工作,获得了不同程度的早熟、高产的效果。为了明确薄膜地面复盖在无籽西瓜采种中的效果,以改进采种技术措施,达到采种量高的目的,我们在1980年开展了薄膜地面复盖采种试验,增产效果十分显著。并将初步结果介绍如下。
Membrane cover the ground cultivation techniques, is a modern melon production of a precocious, high-yielding technical measures. In other foreign countries such as Japan, Italy, France, the United States and other industrialized countries have been applied in production. Currently in Japan, watermelon, melon and cultivation of open field cultivation, almost all of the film to achieve the ground cover cultivation. Played a provincial labor, provincial fertilizer, the role of water, reaching a precocious, high-quality, high-yielding purposes. Since 1979, our country carried out the scientific research on vegetables in the three areas of northeast, north China and northwest China, and obtained the effects of being premature and high-yielding in varying degrees. In order to clarify the effect of film covering on seedless watermelon in order to improve the technical measures of seed collection to achieve the purpose of high seed collection, we carried out film covering test in 1980, and the yield increase effect is very significant. The preliminary results are described below.
