The change of Walnut trees to new varieties is the main method for rapid renewal and improvement of benefits, but unlike other fruit trees, walnuts have lower survival rates. According to our experience, we must pay attention to the following aspects if we want to improve the survival rate of walnut trees.
First, maintaining the proper humidity and temperature of the walnut grafting site is the key to improving the survival rate of the graft.
In the past, the wax was used to seal the scion. When the operation was performed, the wax was easily peeled off, losing its water retention effect and dehydrating the scion. The method of using plastic bags in the grafted parts, although the moisturizing effect is good, but the operation is relatively tedious, now using plastic bag coat newspaper shade, effectively maintaining the temperature and humidity of the grafted parts, greatly improving the survival rate.
Second, the scion quality is good, and the survival rate is high, otherwise it is low. Good quality scion shoots are well developed, 1 to 2 cm in diameter, with a small pith, and at least one full-filling bud, usually 10 to 15 cm in length, free of pests and diseases, unfrozen or dehydrated, and the buds have not germinated or only shoots. Germination, strong vitality. In order to ensure that the high-quality scion is obtained, it is very important that it is properly collected and stored. Scion acquisition time is appropriate in early March and early March. The thickness of the cut branches must be more than 1 cm. The buds should be full and carefully selected. The sick and fragile branches that cannot be used should be removed, and the unsturdy tips should be cut off. The varieties should be sorted and bundled according to specifications (50 per bundle, 50 per bundle). Cm) for storage. The storage of the scion can be a simple storage method for shady wet sand, that is, digging holes in the shady area of ​​the building, 60 cm deep and 100 cm wide, depending on the amount of scion. Place the tied scion flat in the pit and fill it with a clean wet sand. In the storage process can not be accumulated water, can not lose water, can not step on pressure. It is best to put a small amount of wet sawdust into the plastic bag and store it in a cold store at 0-5°C.
Third, control of wound flow is an important measure to improve the survival rate of walnut grafting. Injury flow has always been one of the important factors influencing the survival of changeovers. It is possible to divert water from the sides of the base of the trunk to control the wound flow while changing the connection. The depth of the general kerf is about 1/4 to 1/5 of the dry diameter, and the kerf is staggered more than 5 cm above and below. Drying water in advance is often not effective. After sawing and discharging water in advance, although the injury flow is lighter when the connection is changed, water is still accumulated at the interface, which reduces the survival rate. In addition, when changing the branches of walnut trees, it is sensible to connect the interface to the upper part of the tree to avoid the impact of some bleeding liquid soaking the interface. If there is a lot of water in the interface, open the plastic bag to release the water. If the stagnant water is too long to cause dead ear, you need to make up.
Fourth, the growth of stocking stocks and the roughness of access have a certain effect on the change of survival. Strong tree vigor, changing the survival rate is high; weak tree vigor, change the survival rate is low. Therefore, for a tree that grows weaker, it is necessary to rejuvenate the tree and then change it. Grafting site thickness is generally 3 to 5 cm, the thickness of the tree can be properly increased.
With the improvement of living standards, snack foods have been deeply loved by the masses of the people. When you walk into the supermarket, you will see snacks such as preserved fruit, sour horns, potato chips, almonds, pistachios, fish fillets, dried meat, and spiced fried meat. Snack foods are gradually upgrading to become the daily necessities of the people. As the economy develops and the level of consumption increases, consumers' demand for the quantity and quality of snack foods continues to grow.
Trends in the food and beverage industry, such as consumption upgrades, clean labels, and high protein, are also driving Meat Snacks at an alarming rate, from novelty, unique proteins to the use of raw materials, and innovating, while attracting consumption. Groups and consumption scenarios have also diversified, and many factors are driving the growth and prevalence of meat snacks, including tastes, product claims, and product forms.
