Chestnut soil management
The chestnut growing season should be timely cultivating and weeding, which not only keeps the soil loose, protects the weeds, but also eliminates weeds and reduces the source of pests and diseases. For cultivating and weeding, mechanical or artificial weeding is used. It is strictly forbidden to use herbicides.
The chestnut orchard covering grass should be fertilized and watered in the spring. The hay, corn stover and wheat straw can be covered under the canopy, the thickness is 15-20 cm, the grass is pressed with a small amount of soil, and the soil is pressurized once before June, and the grass is supplemented. the amount. After 3 years of continuous overturning, or digging trenches to cover the grass.
The orchard grows grass, adopts the inter-row grass method, and the grass species can use leguminous grasses such as alfalfa and white clover. The grass is planted with about 1 kilogram per acre, and can be sown from spring to autumn. The sowing depth is 1-1.5 cm. Watering and weeding should be done in time during seedlings. When the planting grass grows into a flat, the height of the grass reaches 30 cm, and it is removed in time, and it is removed about three times a year. Orchard grass is updated 3-4 years.
Chestnut fertilization
In organic chestnut production, chestnut gardens can only be applied with organic fertilizers and biological fertilizers to ensure soil fertility and improve soil structure and microbial activity. It is strictly forbidden to apply chemical fertilizer to prevent adverse effects on the environment and fruit of the orchard.
The production of organic chestnut is mainly based on base fertilizer and supplemented by top dressing. The base fertilizer is generally applied after harvesting chestnut in autumn. The base fertilizer should be organic fertilizer mixed with chicken, cattle, sheep, pig manure and corn stover or green manure which has been fermented or cured by high temperature. The proper amount of microbial fertilizer will be added to the organic fertilizer. better. Apply 4,500-5,000 kilograms of organic fertilizer per acre. The base fertilizer method has the best effect. Usually, strips are used to dig trenches 50-60 cm deep and 30-40 cm wide under the treetops. Mix the decomposed organic fertilizer with the 500 times solution of the live bacteria and evenly apply it to the bottom of the ditch. The upper layer is covered with soil.
Topdressing is generally carried out four times a year. The first three times are sprayed once with 60 times solution of live bacteria before flowering, young fruit, and fruit expansion. It is advisable to spray to the leaf surface every time. It can effectively promote the growth of new shoots of chestnut trees, improve fruit set rate, improve fruit quality, increase yield and increase income. For the fourth time, in the hard core period of the fruit, the water and the live bacteria are diluted at a ratio of 40:1, and the soil layer under the tip of the chestnut tree is perforated, and the diluted microbial agent is poured into the hole, and the soil is covered with water to increase the root of the fruit tree. The ability to absorb nutrients. Use about 1000 ml of Wansheng live bacteria per acre.
Chestnut irrigation
In recent years, the newly developed chestnut gardens have adopted high-efficiency energy-saving irrigation methods, such as sprinkler irrigation and drip irrigation, which have good water-saving effects. Chestnut garden water, water quality should meet the requirements of environmental irrigation water for organic food production. Orchard irrigation can be poured three times in the general year. The first time is to germination water before the germination of the chestnut tree, the second time is the expansion period of the chestnut fruit, and the third time is the winter water after the chestnut is harvested and before the soil is frozen, the three waters should be poured. In the dry years, the water should be replenished according to the soil moisture.
