南瓜藤蔓生长到结瓜的中后期,其生长势逐渐减弱。若利用南瓜蔓节上的不定根,实行压蔓处理,能增加养分供应,使南瓜的产量提高20％～40％。具体作法是: (一)埋茎时间。南瓜埋茎过早易引起茎叶徒长,结瓜数减少;过迟不定根萌发生长慢,对提高产量不利。一般在结瓜2～3批后,藤蔓和叶片开始衰弱,靠根部出现部分蜡黄叶时,进行埋茎为宜。
Pumpkin vine growth to fruiting in the late, its growing potential gradually weakened. If you use adventitious roots on pumpkin vine, the implementation of pressure vine treatment, can increase nutrient supply, so pumpkin production increased by 20% to 40%. Specific practices are: (a) Buried stalks time. Pumpkin stems premature stem easily lead to leggy growth, reducing the number of cucumbers; late adventitious root sprouting slow growth, to increase yield negative. Generally 2 to 3 batches of melons, vines and leaves began to weaken, depending on the root part of the waxy leaves, buried stem appropriate.
