Field management technology of Bailan melon

Bailan melon, also known as Lanzhou melon, formerly known as Wallace, originated in the United States, its thick skin sweet, juicy tender meat, but also has the effect of clearing heat, relieving thirst and diuresis, appetizer and spleen. In our country, it is mainly planted in Lanzhou, so how to manage the cultivation of Bailan melon? Let's get to know it with the editor.

1. Seedling stage management

Generally, the seedlings begin to emerge 10 days after sowing, and the seedlings can be completed in about 2 weeks, and with the growth of the seedlings, the temperature also rises, so it is necessary to do a good job of ventilation and lighting in the greenhouse. In the daytime is to gradually open the two sides of the greenhouse, ventilation, and at night should also be pressed to play a role in heat preservation. At the same time, the ventilation of the small row shed should be larger in order, and the temperature in the row shed is generally controlled between 30 and 32 degrees. When the seedlings grow to 5 true leaves, the small row shed can be gradually removed according to the weather conditions.

2. Auxiliary pollination

In order to improve the yield of Bailan melon, auxiliary pollination is indispensable. It is appropriate to use worker-assisted pollination at flowering stage to ensure normal melon sitting. Pollination is generally carried out in the morning, so the survival rate of pollination is higher.

3. Ventilation and ventilation

Ventilation time and intensity should be determined according to the different growth periods of Bailan melon and the climate of the day, the seedling stage is in early spring, the external climate is changeable, at this time the ventilation should be less, generally only at noon ventilation 3-4 hours. With the growth of seedlings, the external temperature gradually increases, which can increase the ventilation rate and prolong the ventilation time. The temperature in the shed is generally controlled between 30 and 35 degrees in the daytime, but not less than 15 degrees at night. In order to promote fruit expansion and sugar accumulation after fruit setting, ventilation should be increased during the day. Cocoa opened the greenhouse film at both ends of the greenhouse and closed at night. In case of continuous cloudy days, we should pay attention to extend the ventilation time in order to reduce the humidity in the shed.

4. Pest control

The main diseases and insect pests of Bailan melon are quenching disease, vine blight, powdery mildew, blight, leaf spot, virus disease and aphids. The main goal of the prevention and control of quenching disease is to cultivate strong seedlings, and to do a good job of crop rotation in order to improve plant resistance, and can also be sprayed with dimethoate solution; vine blight should be pulled out in time after discovering diseased plants and mancozeb solution in greenhouse; powdery mildew is caused by spraying carbendazim or methyl thiophanate solution once; aphids can be controlled with clean smoke agent or sprayed with 1000 times liquid dimethoate solution.
