西瓜进行早熟栽培,即可调节市场淡季,又可提高经济效益。但是在生产中存在座瓜率偏低、座瓜不整齐、成熟期不一致、采摘时易误摘生瓜等问题。由于这些问题的存在,大大影响了早熟西瓜产量、品质和经济效益。为了解决这些问题,我们采取了如下几项技术措施,取得了较好的效果,现整理出来,供大家参考。一、罩纸帽人工辅助授粉:早熟西瓜座瓜率较低的主要原因是开花期在5月上中旬,气温偏低,昆虫活动少,传粉不充分,影响授粉受精。解决的办法是:糊圆锥形纸帽,于开花前1天下午选发育健壮的花蕾罩住,雌雄花都罩,雄花的数量以雌花的1/3就够了。第二天早上8～11时(天阴时还可推迟),将雄花
Premature cultivation of watermelon, you can adjust the market off-season, but also improve economic efficiency. However, there is a low production rate in the production of melon, melon is not neat, inconsistent maturity, pick mishandled plum and other issues. Due to the existence of these problems, greatly affected the yield, quality and economic benefits of early maturing watermelon. In order to solve these problems, we have taken the following technical measures and achieved good results. Now we have compiled them out for your reference. First, the artificial paper cap hatch pollination: watermelon early melon rate is lower than the main reason is the flowering period in mid-May, low temperatures, less insect activity, pollination is not sufficient, affecting pollination and fertilization. The solution is: paste cone-shaped paper hat, choose the development of robust flower buds live in the afternoon before the flowering day, male and female Huadu cover, the number of male flowers to female flowers 1/3 enough. 8 to 11 am the next morning (days overcast can be postponed), the male flowers
