How to cultivate Castanea henryi with high yield and high quality? How to store it scientifically?

Castanea henryi is a forest and fruit tree species, and the kernel belongs to high-quality dried fruit, and the absorption rate is more than 95%. In addition, the cone chestnut also contains carotene and amino acids needed by the human body, which is rich in nutrition, is in short supply in the international market and has high economic value. the market prospect is very broad. Castanea henryi likes a warm and humid environment, which is suitable for growing in an average annual temperature of 11-20 degrees Celsius and annual rainfall of 1000-1500mm, so how to cultivate Castanea henryi with high yield and high quality? Let's have an editor to take a look at it.

I. the planting method of Castanea henryi

1. Select the land with rich organic matter and good drainage for colonization.

2. After the Castanea henryi seedlings are planted on the above-mentioned land, they are cut short at the 60cm off the ground. After germination, there is a shaping band in the top 40cm of the Castanea henryi seedlings, the branches in the shaping zone are retained, and the branches below the shaping band are cut off. The branches with 3-4 angles and directions are left as the main branches in the shaping zone, and the coring is carried out when the main branches grow to 50-60cm, and each seedling is fertilized with compound fertilizer 1-2kg and farm fertilizer 2-3kg, fertilization depth 35cm.

3. When the Castanea henryi plant grows to the fruiting stage, the sulfur-containing ternary compound fertilizer 1.5-2.5kg is applied to each plant, and the fertilization depth is 20cm.

4. After the fruit was collected, each Castanea henryi was treated with soybean cake fertilizer 1-1.3kg, nitrogen fertilizer 0. 8-1.2kg, phosphate fertilizer 1. 3-1.5kg and farm manure 2-2.3kg.

II. Storage methods of Castanea henryi

1. Sand storage method

The method is simple and feasible and is suitable for chestnut farmers in producing areas. Choose a cool indoor floor covered with 10 cm thick clean wet rent river sand, the humidity of the sand can be clustered by hand, hand loose meaning can dare to open for the degree, the upper layer of a fruit layer of sand interactive layer, each layer 5-10 cm thick, or a chestnut two parts of sand mixed stacking, finally covered with sand I0 cm, covered with straw, the heap height is 0.5-1 m. During storage, turn over and check every 15-20 days to release heat, and rotten grains are picked out from the well. In general, the surface of normal chestnut basically does not touch the river sand, while the rotten grains are stained with clear river sand. In order not to be polluted in the sand period, it is best to choose a clean river copy without soil. Use the sun for 2-3 days before, add 5% clean water, and dissolve 0.1% methyl topiramate in the water. This method can be stored for 2-3 months, and the decay rate is 2% Mel 3%.

2. Cold load method

This is a common method for a large number of chestnut storage at present, because the temperature and humidity of storage are well controlled, the loss of chestnut is less, and the phenomenon of labor basically does not appear, the storage period is long and the effect is good. The stored chestnut should have a full degree of 90% Mel 95%, carbon dioxide no more than 3% mature, bright color, eliminate diseases and insect pests, and should be withered.

3. Controlled atmosphere cold storage method

This is the current chestnut fruit, etc., and graded according to the single grain weight. In the more advanced methods of cold storage, by adjusting the air components of the stored chestnut fruit in the inner village wet sack storage environment, combined with low temperature refrigerated double-layer gunny bags or inner village perforated plastic bags can achieve a good storage effect. In the way of dioxide packaging to maintain the humidity of chestnut. Less than 10% carbon, 5% oxygen, 0 temperature into the cold storage should be stacked scientifically, generally about degree, relative humidity is 90% Murray 95% zigzag or "product" zigzag stacking, under the condition of goods, the chestnut is still fresh and full for 120 days, it should be about 30% from the wall, and the sacks inside the stack are full and of good quality.
