First, thinning and reasonable close planting
When the true leaves of the seedlings are unfolded, dense seedlings and weak seedlings should be used at the appropriate time, and the second seedlings and seedlings can be seeded at the 3-leaf stage. The average early-maturing varieties have a seedling distance of 10-13 cm, medium-maturing varieties of 13-16 cm, and late-maturing varieties of 16-17 cm. When seedlings are transplanted and transplanted, when the seedlings have 4 true leaves, they should be planted with the cotyledon of the cotyledons as appropriate. The row spacing of the seedlings can be appropriately wider than that of the live broadcast. The transplanting age is 25-30 days in autumn and winter. If weeds are present, we must combine the seedlings in time for weeding and weeding.
Second, fertilization
Top dressing should be based on the principle of diligence, early use, and thin application. It should be light in the early stage, heavy in the middle and later stages, and generally dominated by fast-acting nitrogen fertilizers, with appropriate addition of phosphorus and potassium fertilizers. When the first true leaves of the seedlings are unfolded, they should be topdressed with 1 diluted fecal water or 3-4 kg of urea per acre to raise the seedlings; when the seedlings grow to 3 true leaves, the seedlings will be combined with 1 seedlings of fertilization. Transplanting with seedlings generally applies 1 thin fertilizer after 2-3 days after planting, and after that, can apply topdressing fertilizer once every 5-7 days. Generally, it can recover urea 5 - 10 kg and compound fertilizer 10-20 kg. When the plants emerge buds should be topdressed, pay attention to avoid fertilizers falling on the buds, so as not to cause rotten buds. After the main pods are harvested, it is still necessary to continue harvesting the plants on the lateral pods. After most of the main pods have been harvested, they should be topdressed for 1 round of fertilizer to promote the development of lateral pods.
Third, the water
The vegetable heart requires higher moisture conditions, but it is not suitable for accumulation of water. Under normal circumstances, the morning and evening of sunny days should be watered once to keep the soil moist. If new roots of seedlings are not grown after planting and the sunlight is strong at noon, they can be increased by 1 hour of water-breathing at 11-12 a.m. in order to moisten the foliage and sorghum; if it is wet, it should be less. Drench water and avoid water in the area.
Fourth, harvest
In general, when the length of the dish grows to be equal to the height of the tip of the plant leaf (commonly known as Qikou flower) or close to it, it is timely harvested for the appropriate harvest period. The harvesting criteria should also be based on different markets and needs. General market sales, harvest height of 20-25 cm is appropriate; if you want to supply high-level hotels or Hong Kong and Macao, the harvest height of 15-20 cm is appropriate; if you want to export countries in Southeast Asia and Western Europe, the need for long-distance transportation of fresh For long storage time, dishes with fresh vegetables, buds not open, and 12-14 cm in length should be selected.
