Basic introduction of winter snow peach

Winter snow peach fruit, round in shape, flat at the top, narrow and deep in stem pits, with obvious sutures. The fruit is small in size, with an average weight of 89 grams per fruit and 155 grams per large fruit. When strictly thinning the fruit, the average weight of a single fruit can reach 122 grams. The skin has a yellow green background and a red color on the sunny side. The flesh is milky white to milky yellow, and when first harvested, the flesh is fine, hard, and crispy, with little juice; After storage for 1-2 months, the meat is soft, juicy, semi sticky, sweet, fragrant, and contains more than 17% soluble solids, indicating good quality. The local area matures in mid November and is extremely durable. Ordinary indoor soil method storage for about 50 days, basically maintaining the original flavor; Constant temperature controlled atmosphere storage can last for more than 80 days

It was discovered in 1986 in Caojiagou Village, Pingchang Township, Qingzhou City, and was selected through mutation breeding of excellent individual plants. In 1993, it was identified by organizations such as the Forestry Bureau, Science and Technology Commission, and Agriculture Bureau of Qingzhou City. Approved by the Crop Variety Approval Committee of Shandong Province in 1998. Belonging to the northern peach species population

1. Anti anemia, promotes blood production. Peach flesh has a high iron content, second only to cherries among various fruits. Due to the involvement of iron in the synthesis of human blood, eating peaches has the ability to promote hemoglobin regeneration, which can prevent and treat anemia caused by iron deficiency

2. Pharmacological studies on anti coagulation have shown that the alcohol extract of peach kernels can increase the level of AMP in platelets, inhibit platelet aggregation, and exhibit certain anti coagulation and weak hemolytic effects

3. Anti liver fibrosis, Lidan Taoren extract can dilate the portal vein in the liver, promote hepatic blood circulation, increase collagenase activity in liver tissue, and promote the breakdown metabolism of collagenase in the liver, which is beneficial for liver cirrhosis. Liver fibrosis has a good therapeutic effect. It can also increase the flow velocity of red blood cells in the liver microcirculation, promoting bile secretion

4. The bitter almond type and bitter almond enzyme contained in peach kernels have a sedative effect on respiratory organs after hydrolysis, which can relieve cough and asthma<5. The hydrolysis products of bitter almonds in peach kernels, hydrogen cyanide and benzaldehyde, have a synergistic destructive effect on cancer cells. The further metabolites of hydrogen cyanide and benzaldehyde have certain effects on improving anemia and relieving pain in cancer patients. 6. Diuretic and promoting diuresis, reducing jaundice and swelling. Peach blossoms contain polyphenols, which have diuretic effects, can remove water vapor, reduce swelling, and treat jaundice, gonorrhea, and other symptoms. At the same time, peach blossoms can induce diarrhea but have no stimulating effect on the intestinal wall

The tree is robust, semi open, and has a round crown. Both sprouting and branching abilities are high. Branches are thinner, internodes are shorter, and there are more multiple buds. Single buds (leaves or flowers) are also common on young trees or vigorous branches, resulting in lower node positions. Fruits begin to appear three years after planting, and a five-year-old tree can produce around 30 kilograms. All types of fruit branches can bear fruit, with thick and medium short fruit branches being the main ones, and long fruit branches can also bear fruit in clusters. Self flowering and fruiting, high-yielding. When mixed with Qingzhou peaches for mutual pollination, the fruiting strength is stronger. Strong adaptability, drought resistance, suitable for planting on mountain slopes and hilly areas, but prone to fruit cracking during prolonged drought and rain in the later stage. Under the condition of abundant water in plain areas, the surface of fruits is prone to black mold, which affects their appearance

Winter snow peaches have strong branching ability and are prone to canopy closure. It is recommended to have a plant spacing of no less than 4 meters by 4 meters. Pruning is mainly done in summer, with winter pruning as a supplement. During the growing season, it is necessary to promptly remove upright and vigorous shoots, as well as excessive and dense nutrient branches. A summer pruning should be carried out 20-30 days before harvesting to enhance fruit coloring. The tree shape is mainly natural and cheerful, and attention should be paid to tree cultivation. The opening angle of the main branch should be 60 ° -70 °, and the cultivation of lateral branches should be emphasized. The outer branches should be sparse and the inner branches should be dense to prevent the outer branches from being strong and the inner branches from being weak, the crown from being closed, and the fruiting parts from moving outward. Pay attention to the cultivation of fruiting branches in the inner chamber, and carry out short cutting and heart picking of young and vigorous tree bone branches in the summer to promote branching and prevent external strength and internal weakness; Using methods such as removing strong branches and leaving weak ones, removing straight branches and leaving oblique ones, and removing the center to transform the upright branches into fruiting branches. This variety has a large amount of flowers and a high fruit setting rate. When cutting in winter, attention should be paid to the selection and retention of preparatory branches, and the "double branch renewal" method should be used to control the outward movement of the fruiting part

For long fruit branches, it is advisable to cut them short and leave a length of 60-70 centimeters for young and vigorous trees during the initial fruiting stage. By thinning the fruit, 6-8 fruits can be left per branch. Winter snow peaches are prone to producing excessively long fruiting branches, which yield good results. They can be utilized during winter pruning by forcibly bending the excessively long fruiting branches and utilizing the high-quality flower buds on the secondary branches for fruiting. At the same time, they can also produce moderately long fruiting branches at the bending points. Fertilization is mainly based on organic fertilizer, with a ratio of nitrogen, phosphorus, and potassium of 1.9:1:4.6. Special attention should be paid to the demand for potassium fertilizer during the hard core stage and the early stage of rapid fruit expansion. Winter snow peaches have strong flowers and produce clusters, so strict thinning of flowers and fruits is necessary. In addition to combining winter pruning to remove excessive flower buds, fruit thinning should be carried out from late May to early June, leaving 6 fruits on long fruit branches, 4 fruits on medium fruit branches, and 1 fruit on short fruit branches. This can control the yield per hectare at around 30000 kilograms and significantly improve fruit quality. Spraying calcium during the rapid expansion period of fruits can improve their hardness and storage performance

Method of making winter snow peach

Peach jam

Ingredients

600 grams of peach, 150 grams of malt sugar, 90 grams of granulated sugar, 1 lemon, 100cc of water, 80cc of orange wine

Method

1. Wash the lemon and squeeze out the juice for later use; Peel and remove the seeds from the peach, then cut it into cubes for later use<2. Put the diced peach into an acid resistant pot, add water and lemon juice, and bring to a boil over medium heat

3. Reduce the heat to low and add maltose to continue boiling. When boiling, use a wooden spoon to stir continuously

4. After the maltose is completely dissolved, add granulated sugar and continue to stir for 10 minutes. Then add orange wine and simmer until the sauce becomes thick
