The quality of muskmelon is closely related to the maturity of the fruit. If the ripeness of the fruit is not enough, the sweetness is low and the aroma is insufficient. However, when the harvest is too late, the flesh is soft, the flavor is not good, and the food value is also reduced. Proper early harvesting will help improve economic efficiency. Melons, which are generally sold locally, are harvested when they are very mature; melons that are exported to foreign countries should be harvested 3-4 days before maturity and when the maturity is 8-90%. At this time, the harvested fruit is of high hardness and storage capacity. It was also very mature when shipped to sales. The harvest period of melons is: when the sugar reaches the highest point but the flesh has not yet become soft: its criteria are as follows:
Fully show the characteristics of the species. When the fruit is generally ripe, the color of the peel changes to a different extent. Such as from the original green gray green, gray-green or yellow; from white to milky white or yellow; from light green to white. At the same time mature melon skin glossy, clear pattern. Some varieties can also give off aroma. Guttered varieties, mature when the ditch is obvious. A variety of reticulate, fruit surface reticulation highlights when the mark is mature.
Changes in cucurbits, melon tops. Most of the early maturing varieties are easy to detangle, while late-maturing varieties are not easy to detangle. After the fruit matures, the hairs near the cucurbits fall off, the umbilical portion of the guava begins to soften, and the detachment forms around the fruit pedicle, resulting in cracks. For de-pedicated species, the most suitable harvesting period is when cracks appear but have not been detethered.
Plant aging. The tendrils of the fruit must be dry, and the leaves and leaves of the fruit-setting section are chlorotic and the leaves turn yellow.
Flowering to maturity. The time required for flowering and fruit ripening of different varieties varies greatly. 25-30 days for thin-skinned muskmelon, 35 days for early-maturing varieties of melon, and 50 days for mid-maturing varieties; they can be tagged when flowering and pollinating, indicating the date of pollination, according to The fruit development period of the variety is used to determine the harvesting period; however, the fruit development period of the general variety has an activity range of 5-7 days, such as cultivation in the high temperature period, can be harvested 5-7 days in advance, and the cultivation or pruning is not strict during the low temperature period. High water and fertilizer conditions, especially nitrogen fertilizer, when the foliage is lush, it is delayed to harvest 5-7 days.
For example, the harvest standard of Fenglei Muskmelon is: about 35 days after flowering, the peel is yellow-green, the anterior leaf of the melon turns yellow, forms an off-layer, the umbilicus is soft and has aroma. The harvesting standard of Ruilong melon is: about 50 days after flowering, the peel is grayish green, the melon's anterior leaves turn yellow, the umbilicus is soft, there is aroma, the melon becomes lighter, and the reticulates are prominent; the harvest should be in the temperature of melon in the morning Low (below 20°C), when the melon surface is not dew, the melon handle should be cut into a "T" shape.
