Management measures after planting cantaloupe

In the past two years, the planting area of Hami melon in Jiading District has gradually expanded, and the planting varieties have been continuously enriched. In 2007, a total of about 60 mu of cantaloupe were planted, and the main varieties were "Xuelihong", "9818" and "Xianguo". At present, the planting of cantaloupe has been basically completed. In order to ensure the normal growth of cantaloupe, it is urgent to do a good job in the management after planting. The main management measures are as follows:

1. Temperature and humidity management

When heat preservation is covered with multi-film in spring, special attention should be paid to reducing dampness and preventing disease. Try to create a high-light environment, frequently uncover the film under the condition of heat preservation in sunny days, keep the greenhouse temperature at 28: 30 ℃ during the day and no less than 15 ℃ at night, when the melon vine grows to the fruit-setting node position, properly reduce the temperature to promote fruit setting, and increase the temperature difference between day and night during the fruit expansion period to improve the quality. At the beginning of April, the small ring shed can be removed when the external minimum temperature is more than 15 ℃.

2. Fertilizer and water management

The demand for water during the whole growth period of Hami melon is not high, which should be determined by soil moisture, topography and the growth period of Hami melon, which can be irrigated once and twice, usually combined with fertilization.

Fertilization can be based on the growth of the plant, spraying plant nutrient solution after the living plant to promote the growth of the plant, when the plant growth is weak, the leaching solution of compound fertilizer can be used to increase the application of extended vine growth and coarse fertilizer. During the period of melon and fruit expansion, topdressing for 1 or 2 times can be applied at the 30cm off the root, compound fertilizer 10~15kg is used per mu, and foliar fertilizer of potassium dihydrogen phosphate is also applied. During the fruit ripening period of half a month before melon harvest, fertilizer and water must be stopped to prevent fruit cracking.

3. Proper pruning

Pruning strength should be determined according to fertilizer and water conditions and plant growth potential, and should be timely, appropriate and reasonable in principle. Pruning should be carried out when the temperature is high in sunny days, pruning diligently to reduce the wound and reduce the occurrence of diseases.

In the protected cultivation of Hami melon in early spring, single vine pruning is used, that is, the main vine is late to pick the heart, the lateral buds at the base of the main vine are removed, the seed vine leaves 1 or 2 leaves in front of the female flower and pick the heart as early as possible, and the vine without female bud protrudes during the flowering and fruit setting period, which should be removed or left as soon as possible to regulate the distribution of nutrients and promote fruit setting.
