Tangshan small package chestnut manufacturer takes you to know: what should be paid attention to when harvesting chestnut processing plant

Judging from the maturity of chestnut fruit, the harvest period is when about 1/3 of the chestnut buds of the whole tree crack.

When harvesting chestnuts, avoid rainy days, sunny days after rain or early morning dew, otherwise harvested chestnuts are easy to rot. In the production process, chestnuts are harvested after continuous sunshine for several days, so the harvested chestnuts are bright in color, plump in volume, low in water content, good in quality, not perishable, and resistant to storage and transportation.

Let's take a closer look at how to harvest chestnuts.

There are usually two ways to harvest chestnuts: one is to pick chestnuts, and the other is to pick chestnuts.

1： Pick up ripe chestnuts on the chestnut tree, break them apart, throw them on the ground and pick them up. The chestnuts harvested in this way have good development, beautiful appearance, good gloss, high quality, durable storage and transportation, and can make full use of auxiliary labor. But you should pick it every day, otherwise the chestnuts will be exposed to the ground for a long time, lose water, and air dry, which will affect the yield and fruit quality. The test showed that chestnuts exposed to trees one day will lose more than 10% of water, and chestnuts that lose water are easy to mold and deteriorate in the process of storage and transportation. Two types: chestnut cracking more than 40%. Shake off the chestnuts with a bamboo pole, pick them up and put them in the shade. Spray a small amount of water at 20cm of each layer to increase the humidity in the pile. The thickness of the pile shall not exceed 80 cm. After splitting 5-7 crown buds, pick chestnuts and be careful not to damage the peel surface. For convenience and speed, some chestnut growers use sticks to shoot after the chestnuts are broken, which will seriously damage the waxy luster of the peel, and some will cause scratches, which will greatly reduce the grade of the fruit. There is also a combination of the first two methods. In production, the method of picking chestnuts is usually combined with the method of picking chestnut buds. When some chestnuts fall 2-3 days before harvest, you can use the method of picking chestnuts. When 50% of the chestnut buds are broken, they can be harvested immediately or in batches. After knowing how to pick chestnuts, let's know what we should pay attention to when picking chestnuts? First of all, if the chestnut fruit is picked in advance at an appropriate time, the material accumulation in the chestnut fruit is insufficient, the water content is large, the fruit flavor is poor, and the fruit is not resistant to storage. Therefore, when more than half of the chestnuts are broken, the chestnuts should be harvested.

Then the chestnuts were picked in advance, and they were all green. What's the impact?

(1) Reduce the quality of chestnuts: broken chestnuts are immature, not full, lack of nutrition accumulation, poor color, low sugar content, high water content, easy to rot, not easy to store.

(2) Yield reduction: according to years of practical experience, if harvest 15 days in advance, the yield will be reduced by 55.3%; If harvested 9 days in advance, the yield will be reduced by 35.4%; If harvested 3 days in advance, the yield will be reduced by 6.8%.

(3) Easy to damage the tree body: when the chestnut bud is immature, the fruit stalk is firmly combined with the fruit branch, which is not easy to be knocked down. Therefore, hitting chestnuts will knock down many leaves and easily damage the front of the fruit, which will affect the quality of fruit branches and lead to a reduction in production in the coming year.

(4) There are many pests: during the storage of chestnut buds, the fruit borer peach borer is easy to transform into fruit damage, resulting in an increase in the incidence of fruit pests.

(5) Easy and labor-intensive: when chestnuts crack, if it takes 10 minutes, it takes 30 minutes to turn green. The labor cost of greening, picking chestnut sprouts, picking chestnut kernels and storing chestnut sprouts is more than three times that of picking chestnut kernels. At the same time, it also led to the decline of total output, quality and serious economic losses, which were greater than the benefits.

Small package chestnut processing plants should pay attention to post harvest treatment to prevent chestnut water loss and air drying. In the case of more water loss, the sugar content in the fruit will increase, and the life activities will be limited, which will increase the loss of rotten fruits, and the air drying time will be longer. The longer the time, the greater the loss. Therefore, it should be stored in time after harvest to prevent water loss and rotten fruit loss.
