种植无籽西瓜,一般采用育苗移栽和露地直播两种方式。在黑龙江省的气候条件下,露地直播效果不好。因为:播种量大,成本高;出苗率、成苗率低,降低产量;由于花芽分化期经常受到低温影响,雌花的花芽分化不完善,易结出畸形瓜和空心瓜,畸形瓜有时高达70%左右,降低果实商品率。因此,在黑龙江省种植无籽西瓜,必须采取育苗移栽的方式,才能获得高产增收的高效益。无籽西瓜的制种和育苗技术都比普通有籽西瓜困难和复杂,但只要熟悉无籽西瓜的特性,掌握好
Seedless watermelon cultivation, the general use of transplanting seedlings and opencast two ways. Under the climatic conditions in Heilongjiang Province, the direct broadcast effect is not good. Because: large seeding, high cost; emergence rate, seedling rate is low, reduce the yield; flower bud differentiation is often affected by low temperature, flower bud differentiation imperfect, easy to bear deformity melon and hollow melon, malformation sometimes up to 70 % Or so, reduce the rate of fruit products. Therefore, planting seedless watermelon in Heilongjiang Province, we must take nursery transplanting way, in order to obtain high yield and high efficiency. Seedless watermelon seedling and nursery techniques are more difficult and complex than the common seed watermelon, but as long as the familiar seedless watermelon characteristics, good grasp
