1. In the cultivation season, spinach is a kind of vegetable with strong cold resistance. It can be sown at any time from late August to early April. The cold autumn is the main cultivation season of spinach.
2. The soil preparation for spinach has large roots, deep-rooted people, strong water-absorbing power, and drought-resistance. For instance, if the rainwater accumulates in the fields, it will easily cause rot. Therefore, it is advisable to choose a loam soil with good drainage. In order to loosen the soil, more cooked manure should be used as base fertilizer.
3. Seeding in the north generally uses drills. Per acre sowing rate of 7.5 kg. However, seedling emergence is difficult in the early autumn, and sowing in late autumn to increase yield and extend the harvest period should increase the seeding rate. Each mu (1 mu = 667 square meters) can be increased to 10 kg to 15 kg. Spinach with dry seeds sowing germination slower, in order to promote the early spinach seed germination, before sowing soaked with germination, low-temperature germination, break down with seedlings break down after the skin peel germination or seed germination after soaking and other methods. Because different seed treatments are used before sowing, the speed of germination and growth after sowing is different. If you increase the seeding rate, using a variety of methods of seed treatment, you can achieve the purpose of a sowing time harvest.
4. Field management Spinach emerges after 7 to 15 days after sowing. The growth of seedlings is slow and the weeds are easy to breed. When the seedling height is 6 cm to 7 cm, it should be seedlings. Spinach topdressing should grasp the hot days should be thin, cold days should thick; early should be diluted, the principle should be concentrated late. Spinach is a multi-recovery vegetable and should be fertilized after each harvest to promote seedling growth. To accelerate spinach growth and increase yield, gibberellin can be used during growth. It is generally used 10 days before harvesting, with 10 ppm to 15 ppm in the early autumn (1 ppm for 1 ppm, the same below) and 20 ppm to 25 ppm for autumn and winter. After spraying, fertilization is also needed to give full play to its effect of increasing production.
5. Diseases and Insect Pests The major diseases during the growth of spinach are downy mildew and anthracnose; insect pests include aphids and vegetables. Downy mildew and anthracnose control methods, with 200 times Bordeaux spray; 70% chlorothalonil wettable powder 600 times control. The aphids were sprayed with 40% omethoate EC 1500-2000 times. The vegetable mash is sprayed with 5% Ruijin special suspension agent 2000-3000 times.
