How do melons start?

The main vine of melon is weak, and the growth of side vine is very vigorous, so melon is generally dominated by seed vine and grandson vine. Therefore, picking, pruning and heading are very important. So how does melon start?

1. How does melon start?

Generally, when melon seedlings grow to 4-5 true leaves, they are picked to promote lateral branch growth. After the young melon sits down, the vine is picked again to promote the transportation of nutrients to the young melon and promote the expansion of the young melon. The pruning method of melon should be carried out according to the fruiting habits of different varieties.

1. Double vine head: suitable for greenhouse, greenhouse melon hanging vine cultivation, the main vine two leaves one to three leaves one pinch tip, in the lower part of the two healthy vine hanging, each vine on the reservation of a melon, melon before the election to stay two lateral branches (vine), each vine on the selection of three leaves to pick, to ensure that there are an average of 7-9 functional leaves to promote fruit development. Each seed vine can keep up to 4 melons, the whole plant can keep 8 melons.

2. Three vine heads: the main stem is three leaves and one heart to four leaves, and each plant leaves three healthy vines. The first vine leaves a melon at the third leaf, the second vine leaves a melon at the second leaf, and the third vine leaves a melon at the first leaf. Each vine leaves 3-4 vines, each vine leaves 3 leaves after picking, the whole plant leaves 3 melons, fruit maturity and listing more concentrated. There are more than 50 leaves in the whole plant, and each melon has 17-20 functional leaves on average, which ensures that the photosynthetic products of the leaves meet the requirements of swelling melon and sugar accumulation and promotes the normal growth and development of fruits.

3. Four-vine head: the main stem four-leaf heart to five-leaf heart pinch tip, each plant leaves four healthy vine, the first vine can leave a melon in the fourth leaf, the second vine leaves melon in the third leaf, the third vine can leave melon in the second leaf, the fourth vine leaves melon in the first leaf. Each vine leaves 3-4 vines, each vine leaves 3 leaves after picking, the whole plant leaves 4 melons.

2. How can melons be sweeter?

1. Increase the temperature difference between day and night: fruit maturity requires sufficient light and a large temperature difference between day and night (generally above 15 degrees Celsius), and reduce ventilation during the day to increase the room temperature. Higher room temperature is beneficial to the synthesis of sucrose. The synthesis intensity of sucrose at 35 ℃ is twice as high as that at 10 ℃. At night, ventilation should be increased to reduce room temperature and create a growth environment with large temperature difference between day and night.

2. Soil moisture should not be too much: under the premise of normal growth of melon, the absorption of soil moisture and nitrogen should be properly controlled when the fruit enters the mature stage. Due to excessive nitrogen absorption, unstable intermediate products such as nitrate will accumulate in the plant body, and the plant will grow too long and easy to develop diseases. Therefore, it is necessary to cooperate with the application of more harvest, 20 kg per hectare. The fruit should stop irrigation 10 days before harvest, otherwise the melon will not be sweet.

3. Reasonable fertilization: partial application of nitrogen fertilizer, excessive nitrogen, accumulation of unstable intermediate products of nitrate in the body, great impact on sugar content, calcium deficiency in soil is easy to form fermented melon, fruit is not sweet, especially in the middle and late stages of fruit development, nitrogen fertilizer control is very important, organic fertilizer and leaf fertilizer based on trace elements can promote soil ion exchange, increase soil permeability and water capacity, conducive to soil aggregate formation and microbial activities,

Melon head and management are very important, do these work well, melon will be sweeter, must be careful management oh.
