Spinach can also be called persian, red root, parrot, etc., and can be divided by seed form into two variants, stabbing and non-stabbing, rich in carrots, vitamin c, vitamin k, minerals, etc., which is one of the vegetables common on our table. So, what are the techniques for early spring spinach cultivation and what are field management looking at
Early spring spinach cultivation:
1. Preparatory work
Early spring temperatures are still relatively low, and late light is low, and leaves and vegetables are highly susceptible to spiking, so it is important to select varieties that are not easily squirted now. The plots should be strewn with uncultivated vegetables and, after the pre-harvesting, should be ploughed deep in time to clean up the debris. When the soil is unfrozen in the early spring, when it breaks, it is applied to the position of 2,000 kg of rotting organic fat, 25 kg of urea and 10 kg of potassium fat for each acre, which is then ploughed and ready to sow。
2. Seeding
Spring spinach is still growing at a relatively low temperature, and it takes at least half a month to sow if the seed is not only soaked with seed. If the seed is soaked, the seed is first immersed in hot water for five hours, dried up in a 25-degree greenhouse environment, and normally seeded for two to three days, which will significantly reduce the bud's time and promote seedling. There are many ways to sow spinach, and early spring *** is common for wet planting, first to pour bottom water and then to sow seeds once underwater。
3. Field management
Because early spring temperatures are low. It is therefore recommended that a plastic film be covered once so that it will have an excellent warming and humid effect, and attention is drawn to the timely removal of seedlings after they are released, or to the building of a small arch. The purpose of this is to make the seedlings more light-seeming, multi-smelling, and to burn the seedlings at high temperatures, as well as to watch for the small arch sheds to open the night and day and clear the rain cover. Wet spring spinach is used because soil moisture is abundant and water is usually poured once when two to three leaves are produced, followed by soil and climate change. For the second time, 15 kilograms of urea per acre were flushed with water, especially during the first half of the month of harvest。
4. Collection in due time
Spring spinach should be harvested in due time, depending on the growth and production needs. Premature harvest yields are too low, while late harvests are highly susceptible to withdrawal, reducing the value of commodities and affecting eventual benefits. After the harvest, the undertow can be carried with crops such as peanuts or maize, or other crops can be planted。
Spinach field management
Seeds before seeding: water each morning and night。
Seeds after seeding: remove cover and water the seedlings in a timely manner in accordance with soil conditions。
3. Vegetable nursery age: new high-lipid membranes are sprayed in due course to prevent bacterial infestation and to increase the intensity of light co-operation for the growth of the seedlings。
4. Long-term spinach students: repeated, small-scale pursuit of fatty faeces, squirming of squirms to make plant poles thick, foliage thick, foliage tender and strong。
