Empty cabbage originates in the country's tropics and is suitable for growing in the wet zone, mainly in the southern part of the country, where green leaves and vegetables are grown in the summer and autumn. So, what time do you grow empty cabbage? What's the time and method of planting empty cabbage? Let's see
The timing of the planting of empty cabbage
1. Open cabbage field cultivation
The field cultivation of emptied cabbage is generally available for planting in april/july and must be harvested before the frosts fall. Empty cabbage is hot and wet, suitable for wet soil and adequate light. The requirements for soil conditions are not stringent and fatty, so it is important for the northern cabbage to manage the season if they want to grow open-air cabbage。
B. Cardio gardens
In order to achieve high economic benefits, the production and supply of large-scale production can be achieved largely on an annual basis, with planting scheduled for the months of october to december and for the following march。
The method of planting hollow cabbage
1. Post-plant management
(1) sowing
Leaching of seed sprouts with dens at a distance of 35 cm and 15 - 18 cm, with a seed rate of 2. 5 - 3. 0 kg per acre. The seedling plant, which can be marketed in combination with seedlings, is sowed with seedlings and seedlings, which are then covered by 1 cm of soil, and require a bed of 50-60 m2 per acre of seedlings and a seedling volume of around 2. 0 kg。
(2) post-relay management
You'll have to keep it warm. Upon seedlings, when they are 3 cm high, fertilizer management is enhanced and urea is flushed with water at about 5 kg per acre. Drought during seedlings. A seedling of two leaves at a time of about 6 cm. During growth, 20 mg/l achromin solution or cloud size 120 (10 mg to 30 litres of water) can be sprayed once every 10 days and twice in series. The seedlings have been planted in 41,5 leaves。
2. Cardio set
(1) fertilization
High-quality, fertile sandy soil is selected, with approximately 4 m3 per acre of decomposition organic fattening, 50 kg of ammonium phosphate, poaching and dredging, with a width of 1. 0-1. 2 m。
(2) demolition
When broadcast live, seeds are seeded at range (15-18 cm) x 35 cm. Where the seedling is grown, it is established at a distance of 30 cm by 35 cm by 17,120 cm, or at a distance of 18 cm by 35 cm by 3 or 2 cm by 30 days. The seedlings shall be sowed first, and then laid down with earth。
3. Field management
(1) fertilizer management
Vaccination management is to be enhanced by the application of approximately 10 kg of nitrogen per acre, by the two leaves of the cabbage, or by the planting of the plant, so that the soil is humid during its growth. The harvest of seedlings, about 30 centimetres high, is followed by fat for each harvest, at a standard of 10-15 kg urea per acre to promote new occurrences and growth。
(2) cropping
In order to prevent the growth of the plant from lumbering and weeding, it is possible to create an enabling environment for the growth of the plant by lumbering its surfaces, contributing to the growth of its roots。
(3) temperature management
The production of hollow cabbage should be as high as possible. The temperature of shed production does not exceed 35 °c and is kept above 15 °c at night. In order to promote the growth of cabbage, small arch sheds can be added to the solar-temperature room during cold periods。
Cardio pick-up
The extraction of hollow cabbage is generally carried out by strangulation, leaving 9-12 centimetres for the first harvest when the plant is 30 centimetres or more, and the second harvest for the next 15 centimetres when the i-barrell grows, but leaves 2-3 leafs for the next in order to boost more fresh ground and ensure productive production. Since the third harvest, only one or two leafs have been left under each new harvest in order to prevent the occurrence of too many new harvests and premature plant failure. At the same time, overstretched branches of the plant base have been removed in order to meet the objective of updating and maintaining reasonable groups。
