The latest course of management techniques and methods after fruit setting of muskmelon in greenhouse

When planting muskmelon, greenhouse cultivation can achieve high yield and high quality, which is the preferred choice of many fruit growers, and the management of muskmelon fruit setting in greenhouse is very important, which directly affects the yield and quality. So how to manage muskmelon in greenhouse after setting fruit? Come and have a look with the editor.

1. Temperature management

During the fruit expansion period, the temperature difference between day and night should be widened properly, and the temperature in the greenhouse should be controlled between 28-30 degrees during the day and 18-20 degrees at night. Generally, the night temperature is stable above 10 degrees, that is, the inner shed will be removed at the end of March or the beginning of April. When the temperature is slightly lower, the shed can be closed at 4 p.m., first the tuyere will be closed, and when the external temperature is high, the closure of the shed will be gradually postponed to around 5 o'clock or after. This can open the temperature difference between day and night as far as possible, promote the accumulation of sugar in the fruit and improve the fruit quality.

2. Fertilization

The fertilizer and water management of muskmelon during the expansion period is very important, and topdressing needs to be carried out many times. Generally, fruit thinning is carried out in time when the young fruit grows to the size of an egg, and then the first fertilization is carried out, while those with weak growth generally apply the second fertilizer 10 days after the first fertilization, and the nitrogen content of the first fertilizer is higher, and the potassium content of the second fertilizer is higher. Generally, 10-15 kg of ternary compound fertilizer is applied per mu, while water-soluble high-potassium fertilizer or flushing fertilizer is used according to the specified amount of packaging. Furrow irrigation and drip irrigation can be used when fertilizing, furrow irrigation is generally long to short section by section unloading, generally fertilizer and water is hit to the ditch full, infiltrate to the border surface, while drip irrigation is to dissolve the fertilizer and apply it from the dropper. Generally speaking, drip irrigation is better than furrow irrigation. After furrow irrigation, attention should be paid to ventilation so as not to cause diseases caused by excessive air humidity.

3. Keep the fruit reasonably

In the second batch of fruit setting is generally carried out 20-25 days after the first batch of fruit setting, at this time depends on the growth of melons and vines to determine the number of fruits left, generally vigorous growth of each plant can stay 2, and weak growth is recommended to retain one fruit, this can promote or advance the fruit setting of the third batch of melons, and prevent the plant from premature senescence.

4. Harvest

The harvest standard of muskmelon is that when the sugar content reaches the highest point but the pulp has not yet softened, it is necessary to consider whether different varieties have fully shown the characteristics of the variety, and according to the actual maturity. In order to facilitate harvest, you can use pollination time mark, you can also see the change of leaf color after fruit setting, when the leaves turn yellow and scorched, choose the cut melon below 20 degrees in the morning when there is no dew on the surface to harvest.
