Preparatory Work and Transplanting Techniques for Greenhouse Cultivation of Muskmelon
① Transplanting at the right time plays an important role in the early ripening of muskmelon and in improving economic returns. The transplanting period is closely related to the ground temperature inside the greenhouse at the time, so the transplanting period differs from region to region. In the middle and lower reaches of the Yangtze River it is in early to mid-March, in North China in late March, and in cold regions such as the Northwest and Northeast in early to mid-April.

Key Technical Points for Greenhouse Management of Muskmelon After Transplanting
1. Greenhouse temperature regulation After transplanting, in the early stage, in order to raise the greenhouse temperature and promote seedling recovery, the greenhouse film should be fastened tightly, and the straw mats should be uncovered and covered in a timely manner; before flowering and fruit setting, the daytime greenhouse temperature should be maintained at 25-28°C, and at night at 16-18°C. When the greenhouse temperature exceeds 28°C, the greenhouse film should be opened for ventilation. As the plants grow

What are the causes of melon fruit abortion and the control methods?
1. Causes of fruit abortion 1. Temperature too high or too low. When the temperature is too high, photosynthetic accumulation is low and respiration consumption is high, which easily causes the vines to grow excessively, leading to malnutrition and fruit abortion; when the temperature is too low, the root absorption capacity weakens, affecting photosynthesis and leading to nutrient deficiency and fruit abortion. 2. Soil too dry

How can the sugar content of thick-skinned melons grown in solar greenhouses be increased?
In recent years, the area devoted to cultivating thick-skinned melons in solar greenhouses has grown larger and larger. Because growers single-mindedly pursue yield, the sugar content of thick-skinned melons is low and prices have fallen. Therefore, how to increase the sugar content of thick-skinned melons has become a key technical measure in cultivation.

What to Do About Low Fruit Set in Plums? Cause Analysis and Methods to Improve It
1. Regulating tree vigor For excessively vigorous trees, promptly remove buds and prune upright branches, and promptly open up the branch angles; alternatively, in autumn or spring apply 3-5 g of 15% paclobutrazol per tree, or spray 150-200 times diluted paclobutrazol or PBO after petal fall. For trees that are too weak, apply base fertilizer after harvest, and promptly apply topdressing and foliar fertilizer during the growing season.

Practical experience sharing on growing plums in greenhouses
In order to explore the early fruiting and early high-yield techniques of cultivating plums in greenhouses, our station conducted experimental research from 1997 to 2000. The greenhouse was covered in the winter of the second year after planting, and in 2000 a 4-fen plot greenhouse produced 1000 kg of plums. The output value was more than 10,000 yuan, and the maturity period was about 60 days earlier than open-field cultivation. Through the experiment
