Warm winter sheds are planted in high density resorts, where 1-2 year old seedlings of open field finished products are transplanted into high density resorts in greenhouses and then moved to open areas in winter. Generally, 2,000 667 meters of income can be produced per 667 meters2. Up to 30,000-50,000 yuan, the economic benefits are considerable, and its main cultivation techniques are as follows.
First, choose strong seedlings timely planting incense sticks intolerance of low temperature, if the damage by the cold, the top buds were frozen, frozen cortex, and then into the greenhouse and cultivation will result in a significant reduction in production. Therefore, we should generally raise seedlings before the arrival of Yanshuang. It is usually appropriate to raise seedlings from open ground from late October to early November. When raising the seedlings, special attention should be paid to the integrity of the root system. The length of the main root should be maintained at 20-25 cm and the secondary root should be 10-15 cm. Weak seedlings, diseased seedlings, severely injured seedlings and over-emergence seedlings should be removed. The criteria for strong seedlings are: seedling height 1.2-1.5 meters, stem diameter 1.5 centimeters at 10 centimeters above the ground, high degree of lignification, full organization, and full top buds. Digging the false sloping ditch at the leeward position will plant the seedlings obliquely to be planted. Generally, the spurs will be planted for 15-20 days. When there are cold currents, they need to be covered with cold.
Second, buckle shed colonization
1, planting time is generally in the middle and late November buckle shed, buckle shed 5-7 days to plant.
2. Soil preparation and soil preparation before 10 days of planting, 5,000 m 2 per 667 m of composted organic fertilizer, 20 kg of urea, 15-20 kg of diammonium phosphate, 15 kg of potassium chloride, 25% carbendazim powder 1 - 2 kg, deeper measures will be applied, and will be made into a 1-1.2-meter-wide flattening between north and south.
3, colonization method before colonization with 10X10-6 ABT rooting powder soak 1 hour, can promote root premature hair. And then according to the spacing of 4-5 cm X 20 cm of the specifications cultivation, filling depth of the original seedlings buried line shall prevail, after planting water, solid, generally every 667 m 2 can be planted 60,000-80,000.
Third, strengthen the greenhouse temperature and humidity management
1, the temperature after planting the greenhouse temperature control during the day is appropriate to 20-25 °C, to 25 °C to release the wind in time; at night to control in 10-15 °C, generally not less than 10 °C below, the temperature is high, the bud grows fast, not easy to color and The taste is poor; at low temperatures the shoots grow slowly and the yield is low.
2. Humidity Due to the fact that the root system will inevitably suffer from different degrees of damage, the water absorption capacity will be reduced. Therefore, maintaining high soil moisture and air humidity is one of the important management measures. After planting, it is necessary to pour a large amount of water, and then depending on the type of soil and dry and wet conditions, pour small water at any time to keep the soil moist. The air humidity should be kept above 85%. At noon on sunny days, sprayers can be used to spray water on stems and in the air to increase the humidity in the shelter.
3, light to maintain 20,000 -3 million lux weak light is better, if the sun is strong, can be suitable fork placed grass shade.
Fourth, fertilizer and water management budding to harvest generally do not top-fat watering, axillary buds harvest time every 15 days top dressing once, every 667 meters 2 follow-up urea 15-20 kg, top-dressing after watering, but also for extra-root fertilizer.
V. Pest Control When rust or powdery mildew occurs, use 20% of Triadimefon 500-1000 times spray. When root rot occurs, use 50% carbendazim WP 500-800 times to irrigate roots, 0.5 kg per plant. Irrigation once every 7 days, even irrigation 2-3 times.
Sixth, timely picking the general buckle shed 45-50 days, when the camphor bud grows to 20 cm color well, can be picked on the market. If the time is too short, the output is low, if it is too long, the quality will be declining. After the top buds are picked, the lateral buds will be picked up and bundled into 100-200 grams of small bundles, packed in small plastic bags and sealed to prevent loss of moisture. If you are not in a hurry to go public, you can place the single layer in a cool place with the humidity kept at 0-10°C. You can store it for 10-20 days and avoid stacking.
VII. Transplanting
In mid-April, camphor buds were basically harvested, and a large number of open fields were sold on the market. Prices fell. This period is the best time for transplanting in Pingshuo. The method is to cut the toon seedlings at 10-15 cm from the ground, and then remove them. Outside the greenhouse is planted in Daejeon.
