Planting Techniques for Autumn Spinach in Greenhouses

In the early period of the growth of the greenhouse, autumn spinach can be grown without growth (ie, open field growth), and then the greenhouse film is grown before the frost is frozen. The harvest time is in early November. There are considerable economic benefits from planting autumn sheds, and management methods are simple. The specific approach is as follows:

1 Variety selection

The varieties with high cold resistance, fast growth rate, high yield, and strong disease resistance were selected such as spinach hybrids, spinach hybrids, omnipotent energy, and bipotal crown energy.

2 Site Preparation

Loosen the vegetable field and loosen it once. 667? High-quality farmyard fertilizer 5000kg, poor fertility appropriation of 45% ternary compound fertilizer or 15% Spokesman. Mix the organic fertilizer with the alumina, and smooth it.

3 Scientific sowing

It is usually planted from late August to early September. When sowing, spread the seeds evenly on a flat surface, sowing the seed at a depth of 1 to 1.5 cm, and then step on it again. It is best to use drills. Line spacing is 8 ~ 10cm. General 667 sowing pure and full of seeds about 4kg.

4 Shelter Management

4.1 Temperature

Before the next frost, usually in the middle and late September with a large film, the daytime, the evening of the greenhouse film to be uncovered, and later with the outside temperature decreases, the film was uncovered during the day and closed at night. When the temperature is lowered again, the skirt must be sealed during the day. Encountered high temperatures can open the greenhouse door and uptake for ventilation.

4.2 Moisture

4 to 5 days after sowing, it is necessary to produce seedlings, timely watering before and after emergence, to 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.

4.3 Disease Prevention and Control

In the autumn greenhouse, spinach is easy to get downy mildew, spray 72% of cymoxanil, manganese zinc (glucose) 600 to 800 times liquid after watering 2 to 3 days before detaining the greenhouse film. After the shed was found, 10% of chlorothalonil smoke agent was used to produce 300~400g/667 of 10% chlorothalonil, applied once every 7 to 8 days, and continuously controlled 2 or 3 times to effectively inhibit the spread of downy mildew. .

5 timely harvest

At the end of October, when the plant height is 20cm, it can be harvested. By the end of November, harvesting can be completed. Every 5 pods can harvest 20-30kg.
