Shannon plastic greenhouse planting technology
Cultivation Techniques 1. Nursery It is better to use the seedlings grown in greenhouses, with low stout tops and full heads, and to adopt appropriate technical measures for seedling cultivation: generally sowing from late March to mid-April, soak the seeds in warm water for 15 to 20 hours before sowing. , and then soaked with water for 10 hours, remove the germination, until the seeds exposed buds before sowing. 23 to 37 kilograms per hectare are used. After sprouting, the seedlings will be planted with time, and 12 to 150,000 per hectare seedlings will be planted. Weeding will often be performed on loose soil and a small amount of top dressing will be used in combination with watering. 7 to 8 months is the key to seedling shoots, in order to control its high growth, so that it does not produce branches, increase the number of terminal buds, generally only 0.8 to 1.0 meters tall, about 1 cm diameter strong seedlings, and Secondary seedlings can be cultivated: mainly for the re-cultivation of one year old weak seedlings and winter seedling seedlings. 2. Colonization From late April to early May, these nursery stocks were transplanted into nursery gardens. The plant spacing was 20 centimeters and 40 centimeters, about 120,000 plants per hectare, and buds were promptly wiped after germination. Each plant retained 2 to 3 buds. , And timely fertilizer, watering and loose soil weeding, 6-7 months also have to shoot, focus on controlling the growth of strong growth branches, making it produce more branches and other weak branches growth, can be cultivated into high in the autumn leaves 0.8 to 1.5 meters, with 2 to 3 branches of long and strong seedlings. 3. Post-planting management (1) Plastic sheds: In November and mid-November, lees were selected to build sheds in the sunny area of ​​Yangyang, and a slope-heating plastic greenhouse was adopted. In winter, the required temperature can be achieved without the use of fire and heating, and a shed can be used for many years. General greenhouses are 30 to 40 meters in length, 8 to 10 meters wide in the north and south, and an area of ​​240 to 300 square meters. Brick walls or earth walls are built on three sides of the east, west and north. The wall is 1 meter thick and the back wall is 1.8 to 2.0 meters high. The walls of the two ends are high in the north and low in the south, with a height of 0.8 to 1.0 meters at the southern end and a height of 2.3 to 2.5 meters at the highest point. Four rows of columns are set up from the north to the south, with an interval of 2 meters. The bamboo pillars are used to form the east-west skeleton on the columns. Every 60 to 70 centimeters of it, a bamboo truss is used to form a north-south shelf and the top is covered with a dripless plastic film. (2) Transplanting into the shed: Transplanting into the shed time After 15 days of defoliation, the saplings of the saplings of the saplings are suitable to be carried out in the middle or late of November. The saplings of the saplings have a dormant period of low-temperature physiology for 17 days, and they are usually transplanted into the shed first. After being sealed with plastic film, seedlings should be filled with full-filled, full-grown 1 to 2 year-old seedlings. Before transplanting, the seedlings should be divided into heights of 0.5 m or less, 0.6 to 1.0 m, and 1 m or more. Planted in the southern section, planted in the north section, and planted in the middle section in the middle section. When transplanting, it was first formed into a 1-meter-wide north-south pod in the shed, applied basal fertilizer, and dug the hoe into a depth of 20 cm. In the pit, the seedlings are closely arranged in the pit, the soil is scattered into the raft and the roots of the seedlings are buried, and then water is poured, and the planting density in the greenhouse is limited to the roots. In general, 200 seedlings per square meter are planted at 1 year, and 100 to 150 seedlings per square meter for 2 years. (3) Management of greenhouses: After transplanting into greenhouses in early December, nursery stocks were used to catch light during the day and covered with straw curtains after 5 pm. At 9 o'clock in the morning, the drafter drafted the light to catch the temperature so that the shed was about 20 degrees Celsius during the day and 10 degrees Celsius at night. After 40 to 50 days, the fragrant saplings begin to germinate. 4. reward When the axillary bud grows to 20 centimeters, it can be picked. Generally, from the beginning of February to the end of April, a citron can cultivate a batch of vines every 3 to 5 days. By the end of April, the protection and cultivation of plastic greenhouses will be completed. The seedlings in the shed can be transplanted to the nursery and then cultivated for reuse in the winter.
