Pomegranate is tender and juicy, has a unique taste, has certain medicinal value and health care value, and is loved by many customers. Its exocarp color is one of the key qualities of fruit. Red-skinned pomegranate has a great market in China because of its excellent appearance and wonderful metaphor. So is there any way to help pomegranate color? Share it with everyone.

First, the coloring method? 1, coloring time

If it is bagged pomegranate, it needs to be bagged and colored immediately from the middle and late August to the middle and early September. Generally, the bagging time is 20-25 days before fruit harvesting.

2. Pick leaves and turn them into fruits

This method is an auxiliary way to promote the overall coloring of pomegranate fruit. Picking pomegranate leaves is divided into several times. The first fruit thinning and fruit setting was carried out in the middle and early June. Removing the leaves covered with fruit rust at the base of Populus simonii and fruit stalks can not only reduce the harm of diseases to fruits, but also facilitate the practical operation of fruit bagging. The second leaf picking was carried out in late August before fruit coloring 15-20 days. At this time, the leaves or branches that block the sunlight from shining on the fruit rust are removed or thinned to achieve the purpose of coloring the fruit.

Step 3 spread reflective stickers

In this way, from the middle and late August to the fruit harvest, laying silver-white reflective stickers under the pomegranate trunk or in rows can significantly improve the color of the trunk and the fruit with insufficient light on the upper part. After the film is laid, the branches should be moderately stretched to make the light spots on the trunk road surface evenly distributed.

Step 4 spray foliar fertilizer

In this way, spraying low-concentration potassium dihydrogen phosphate or ammonium sulfate, plant ash soil solution and other trace element fertilizers on pomegranate leaves every 10 day in the middle and early August can promote pomegranate fruit coloring, improve fruit quality and alleviate the practical effect of pre-harvest fruit cracking.

Second, common problems When picking pomegranate bags, we should pay attention to the climate problem, pay attention to the high temperature weather and strong light to burn the peel, and reduce the fruit quality. Before harvesting pomegranate, we should seriously drain water 10- 15 days, especially in plantations with irregular water injection in hilly areas and plains, and harvest them immediately in case of drought and little rain.
