The characteristics of cultivation of autumn spinach in greenhouses are that, in the early growth period, the growth of the greenhouse film (ie, open field growth) can be prevented in the greenhouse, and the film is grown in the greenhouse before the frost is frozen. The harvest time is in early November. At the same time, it can also be woven film cultivation. There are considerable economic benefits from planting autumn sheds, and management methods are simple. The specific approach is briefly described as follows: Variety selection. The use of spinach hybrids, spinach hybrids, omnipotent energy, and bisphenol-crown energy, etc., have strong cold resistance, high growth rate, high yield, and strong disease resistance. Land preparation. If the fruit crop is grown in the Shangyu (generally producing more than 5,000 kg of organic manure per acre), this manure can be dispensed with only 45% tricomponent compound fertilizer or 15% Scatterfew. The specific approach is to loosen the land once and for all. If Shangyu produces vegetables and causes soil shortage, it will produce about 5,000 kg of farmyard fertilizer per acre. Mix the organic fertilizer with the alumina and turn it flat to wait for sowing. sowing. It is usually planted from late August to early September. When sowing, spread the seeds evenly on a flat surface and sow the seeds to a depth of 1 to 1.5 centimeters. Then, step on them again and pour on the water. It is best to use drills. Line spacing is 8 to 10 cm. Generally, about 4 kg of pure seeds are sown per acre. If the seeds are of low purity and impurities, they can be used to remove impurities and alfalfa seeds, and the remaining seeds will be sown to ensure that they will emerge neatly and grow stronger. Management after sowing. 1 temperature. Before the next frost, generally in the middle and late September, the greenhouse film is sealed. At this time, the temperature is still high during the day. During the day and night, the feet of the shed film should be uncovered. After the outside temperature is lowered, the feet will be lifted during the day and the night. close. When the temperature decreases again, the feet should be sealed during the day. If you encounter high temperatures in the future, you can open the greenhouse door and uptake for ventilation. 2 moisture. 4 to 5 days after sowing, the seedlings are to be seeded. Water is poured on the surface of the soil before emergence, and the surface is watered after emergence. In short, we must ensure that the surface of the bauxite is moist to promote the growth of spinach. 2 to 3 days before the film is used to pour water once. After the film is buckled, it is not necessary to water before harvesting. 3 disease prevention and control. In the autumn greenhouse, spinach is easy to get downy mildew, and it is very important to do well in prevention and control. In the buckled greenhouse film 2 to 3 days before watering, it is necessary to spray 1 time to prevent downy mildew agents such as 72% cymoxanilium manganese zinc (glucose) 600 to 800 times liquid. After the shed, if downy mildew occurs, it must be treated with a smoke agent. For example, if 10% chlorothalonil smoke agent is used at 300-400 grams per acre, apply once every 7-8 days, and continuously control 2-3 Second, it can effectively inhibit the spread of downy mildew. Harvested. At the end of October, when the plant height is 20 centimeters, it can be harvested. By the end of November, the harvest will be completed. For every 5 square meters, 20 to 30 kilograms can be harvested.
