Pruning method of thick-skinned melon

The main results are as follows: 1. in the pruning mode of mid-early-maturing varieties, the single fruit weight of mid-early-maturing varieties is generally less than 1.5 kg, and the mature period is 35-42 days. According to the different cultivation season and environment, the following pruning methods can be adopted. The main results are as follows: 1. Cultivation in winter and spring in greenhouse. Generally use the mother vine as the main vine, single vine double-layer melon way, that is, in the mother vine 11-14 nodes to leave the first layer melon, leave 1 melon; in the mother vine 20 nodes more than the second layer melon, leave 1-2 melons. This kind of melon retention method can not only harvest early and go on the market, but also obtain higher yield, so the benefit is better. 2. Early-maturing cultivation in spring in large and medium arch shed. You can use Gemini vine as the main vine and leave double melons at one time, that is, when the seedlings grow to 5 true leaves, leave two strong and similar sub-vines as the main vines, each leaving one melon on the 8-12 nodes of the sub-vines. For early maturing cultivation in spring, because the suitable growth period of thick-skinned melon is short in the arch greenhouse, it is difficult to retain melon many times, and the ventilation and light transmission condition in the arch greenhouse is better than that in the winter warm greenhouse, even under the same cultivation density as the winter warm greenhouse. Double vine pruning can also make the plant grow normally, and leaving double melon can greatly increase the yield of early spring stubble. 3. Delayed cultivation in winter and autumn in greenhouse. It is appropriate to take the seed vine as the main vine, single vine and single melon to keep the melon, that is, pick the heart when the seedlings have 4-5 true leaves, leave a strong vine as the main vine, pollinate at the 10-15 nodes of the vine, and leave 1 melon. Second, the pruning mode of middle and late maturing varieties. The single fruit weight of middle and late maturing varieties is generally more than 1.5 kg, and the mature period is 42-50 days. When the mid-late maturing variety is cultivated in Gongpeng in spring and delayed in autumn in warm winter greenhouse, the pruning method of the mid-early maturing variety mentioned above can be adopted, or the pruning method with mother vine as main vine and single vine can be adopted, that is, the melon can be pollinated at 12-15 nodes of mother vine. When precocious cultivation of winter and spring in winter and spring is carried out in a warm greenhouse, it is best to adopt the pruning method of taking seed vine as the main vine and single vine and double melon, that is, picking the heart when the seedlings are 5 true leaves, leaving a strong son vine as the main vine, pollinating at 10-14 nodes of seed vine, leaving two melons with the same growth or adjacent nodes of pollination on the same day, which can be harvested early and ensure the quality and yield of melons. At present, in the cultivation of winter and spring, some melon farmers use middle and late ripening varieties, with mother vine as the main vine and multi-layer melon retention, to remove the bottom melon when the melon is not mature (otherwise affect the sitting and growth of the upper melon). Although this way of pruning and retaining melon can obtain higher yield, but the quality of melon is greatly reduced, so it is not advisable.
