The fields with high groundwater level shall be drained in time after irrigation to prevent the seed potato from rotting. In order to promote the early growth and rapid development of seed potato, increase the temperature and humidity to achieve neat, uniform and strong seedlings, and cover the film in time after irrigation. The key point of putting mosquito repellent net is to confirm that pests are not attached to leaves, soil, etc. It is important to treat with drugs when necessary. If harmful organisms are found, they should be disinfected as soon as possible.
The seeds are scattered in the 4 gallon nursery pots and covered with soil 2 thicker than the seeds. Apply organic fertilizer once a month. After applying compound fertilizer or digging a pit, bury the organic fertilizer in the soil and water it. When there are 2-3 true leaves, the seedling spacing is 3-4cm. Apply water and fertilizer according to the seedling situation and weather, mainly rotten human feces and urine. In frost and ice and snow weather, plastic film and shading net shall be covered for thermal insulation, which can be covered by small arch shed. Generally, the method of sowing is adopted.
When sowing, evenly sprinkle seeds on the flat border, with a sowing depth of 1-1.5cm, tread again and then pour water. Drill sowing is most used, with a row spacing of 8 ~ 10cm. Generally, about 4kg is sown per mu. After the harvest of autumn vegetables and the day before sowing, do not remove the greenhouse film. Generally, continuous cropping is avoided, and formula fertilization technology is adopted. Before overwintering, spinach seedlings are 10 cm high, and overwintering fertilizer should be applied once according to the growth situation.
Spinach likes sandy loam rich in organic matter, has strong salt and alkali resistance, and the suitable soil pH value is 7.3 ~ 8.2. When the soil is acidic, it can lead to yellowish brown leaf tip and leaf edge, brown root system and even death of spinach. The low temperature is not lower than the growth of the host, but the bacteria can still move, so the low temperature and high humidity conditions in the seedling raising period are conducive to the disease. Sporangium filiform or branch lobed, or irregularly expanded.
The root system faces the ditch wall. The lower part of the root system and seedlings are covered with 1.5 gallon pots soil and closely contacted. The upper part is not covered with soil. After burying one layer, the second layer is stacked until it reaches the storage ditch and is flush with the ground. 50 cm from a ridge, 2 rows per ridge, 5 cm in a hole, 2 seeds per hole, generally about 1 kg per mu. When summer spinach is planted in sandy soil, water 15 is easy to infiltrate or evaporate, and border planting can be used.
Watering should be frequent, less and clear, once in the morning and once in the evening. As the seedling area grows, reduce the watering times and keep the soil moist. Avoid flooding and pay attention to waterlogging after rain. It is estimated that sowing is generally arranged in stages from mid May to early July. It is easy to bolt in advance and difficult to control diseases and pests. If topdressing, it is best to use nitrate nitrogen fertilizer, and pay attention to the combined application of leaf fertilizer.
