1播种时期的确定各地的气候有很大差异,播种时间也不同,南方地区由于气温较高,播种时间偏早,而北方地区气温较低,一般的播种较晚,但采用早熟栽培时间也可相应早播。春季露地直播栽培,一般以当地终霜已过,地温稳定在15℃左右时为露地播种的适宜时间。播种的最佳时间,还应根据品种、栽培季节、栽培方式以及消费季节等条件来确定。一般3月中、下旬播种育苗,4月中、下旬定植,6月下旬开始收获上市;秋西瓜7月上、中旬播种,9月下旬开始采收上市。
1 sowing time to determine the climate there are very different, sowing time is also different, because of the higher temperatures in the South, sowing time is earlier, and the northern temperature is lower, the general planting later, but the use of precocious cultivation time can be Corresponding early broadcast.

The best time to sow, should also be based on varieties, planting season, cultivation methods and consumer seasons and other conditions to determine. Generally in mid-March, late seeding nursery, planting in mid-April, late, harvest began in late June listing; autumn watermelon in July, mid-seeding, harvesting in late September began to market.
