压蔓是覆膜西瓜田间管理中的一项重要技术措施。我省春、夏季节气候干旱多风,幼嫩的西瓜叶、蔓和果实很容易遭受风吹引起损伤,所以需要给西瓜及时压蔓。地膜西瓜的秧蔓比露地栽培长得快。压蔓工作一定要适当提前进行(一般要在瓜蔓长到30—50厘米长时开始压)。因此,西瓜适时压蔓对实现高产、优质、高效至关重要。 1、压蔓的作用。一是可以固定秧蔓的位置。用埋土、压石块和插枝叉等方法,把旺盛伸长的瓜蔓,牢固地固定在地面上,防止风吹翻蔓,不使幼果受伤,对提高坐瓜率有极好
Manchurian is coated with watermelon field management of an important technical measure. Spring and summer weather in our province arid and windy, young watermelon leaves, vine and fruit are easily subject to wind damage, so the need to pressure watermelon in a timely manner. Plastic film watermelon seedlings grow faster than the open field cultivation. Crimping work must be properly carried out in advance (usually in the melon grow to 30-50 cm long pressure). Therefore, timely watermelon crushed to achieve high yield, high quality, high efficiency is crucial. 1, the role of pressure Man. First, you can fix the location of seedlings. With buried, pressure stones and cuttings and other methods, the strong elongation of melon vine, firmly fixed to the ground, to prevent the wind turn over the vine, not to young fruit injury, improve the rate of sitting with excellent
