Qianxi chestnuts have a long history. When do they ripen and how are they grown?

Qianxi chestnuts have a long history and are a traditional specialty agricultural product of Hebei Province. The shells are bright and glossy, the flesh is pale yellow, the inner skin is relatively easy to peel off, and the texture is soft, glutinous and aromatic, with high nutritional value.Qianxi chestnuts what is the market price per jin? When do they ripen? How are they grown?

1. What is the market price of Qianxi chestnuts per jin?

The market price of Qianxi chestnuts depends on the specific market. In some places the purchase price is 8-10 yuan/jin, while in others it is slightly lower. Of course, the size of the chestnuts also affects the price, with larger ones fetching a higher price.

2. When do Qianxi chestnuts ripen?

Qianxi chestnuts, also known as Jingdong chestnuts, are produced in the area of Qianxi County, Tangshan City, Hebei Province. There are about 125 nuts per kilogram. The nuts are uniform and neat with excellent quality, and they generally ripen in mid-September each year.

Grafted chestnut trees begin to bear fruit in 2 to 3 years, while seedling chestnut trees bear fruit in 5 to 8 years, and after about 20 years the chestnut trees enter their peak fruiting period. Chestnuts have a cultivation history of at least more than 2,500 years in our country. They are highly adaptable, widely distributed, easy to cultivate and high-yielding, and can be grown economically on mountains, sandy beaches and other sites. They prefer light, and can be cultivated in soil with a pH of 4.5 to 7.5, an average annual temperature above 10 degrees, an average growing-season temperature of 16 to 20 degrees, and a minimum winter temperature of minus 25 degrees.

3. How are Qianxi chestnuts grown?

1. Spring is the period of flower bud differentiation, spring bud sprouting and flowering of chestnut seedlings. To ensure increased and abundant yields, management must be genuinely strengthened.

2. Watering: Spring is the period when the various organs of the chestnut are built up intensively, and metabolism and nutrient processes urgently need water. Irrigation before early-spring sprouting can promote female flower formation and benefit branch growth. When planted in mountainous and hilly areas, the soil layer is relatively thin and has poor moisture retention, so it is necessary to spray New High-Fat Film in time and cover with grass to preserve moisture.

3. Bud removal: When the buds sprout, remove excessive buds from the middle and lower parts of strong branches, leaving 4 to 5 large buds, and leave 2 to 3 buds on medium branches. Bud removal is carried out according to the principle of removing the lower and keeping the upper, and removing the dense and keeping the sparse.

4. Within two years after grafting, some branches grow excessively and conspicuously, which will suppress the growth of other branches and affect canopy formation. Therefore, when the new shoots begin to grow in spring, spray Flower Promoter No. 3 in time to make plant nutrients flow back and inhibit the rampant growth of branches. Without artificial topping of terminal buds or killing of shoot tips, it can inhibit the rampant growth of main shoots, superfluous buds and side hearts, convert growth nutrients into reproductive nutrients, promote flower bud differentiation and improve the quality of pollen fertilization. More flowers, more fruit set, prevention of fruit drop, and promotion of development.

5. Emasculation: Without artificial control, the ratio of male to female flowers in chestnut is generally 20 to 50:1. Excessive male flowers consume a large amount of nutrients and reduce yield. Therefore, most male inflorescences should be removed when they are 2 cm long, leaving only the topmost 3 to 5 inflorescences on the new shoots, so that the ratio of male to female flowers is maintained at around 5:1. In addition, increasing potassium fertilizer application also helps inhibit excessive growth of male inflorescences.

6. Fertilization: For chestnuts to be high-yielding, in addition to conventional application of nitrogen, phosphorus and potassium fertilizers, the key is to apply Fruit-Stalk Strengthener, boron fertilizer and zinc fertilizer. When female inflorescences appear, spray a mixed solution of Fruit-Stalk Strengthener plus 0.2% borax and 0.2% zinc sulfate, once every 7 days, for 2 to 3 consecutive sprays. This thickens the fruit stalk and increases nutrient transport. It prevents flower drop, fruit drop, fruit cracking and stiff fruit, and gives beautiful fruit shape and good taste.
