1. The selection of suitable species for use is good, productive, resilient, and cold-resistant coloured saloons, such as red leaves, red leaves, etc。
The whole area of fertilisation is selected for flat ground, soil fertility, easy drainage and low weed, with 15 - 20 centimetres of deep cultivation at the beginning of november, combined with 3,000 kg of high-quality decomposition organic fertilizer per acre and 25 kg of ammonium phosphate as base fertilizer. Then we're going to do a 1-1. 2 metre-wide flat, fine-skinned, up and down。
In the second half of november, seeding will take place in due course. Before sowing, the bottom water is sown with 3 - 4 kg per acre, the seeds are evenly sown to the surface with appropriate fine sand, and a foot is stamped or covered with a faeces, covering the membrane. A small arch with a two-metre piece of bamboo, which is 70 cm tall and 80 cm tall, is then used, with a thin film。
Improved management is based on a bottom-water basis, free of water before seeding, and available for five to seven days. When the leaves were excavated, the membrane was removed for the first time in the field to remove grass seedlings. A second weed-weed sapling is carried out when the two leafs are grown, and the first fattening is pursued, the first water is poured, the average acre is followed by 10 kg of nitrogen phosphorus compound fattening, the second water fertilizing in 15 days, the acre is combined with 5 kg of compound fertilizing, and each subsequent harvest is followed once, each time 5 kg - 10 kg - or 1,000 kg of urine per acre. At the end of march of the following year, temperatures rose, allowing for evacuation to small arch sheds, improved ventilation, the prevention of high-temperature burning seedlings and the prevention of leachate rusty。
The proper collection of pick-up vegetables can take up to 4-6 leaf leaves, 10 cm high and 15 cm high, and be replanted so that they can be collected in batches until early june. Care is taken to increase production by keeping a small and balanced stock of each harvest。
