Blood Bich Choi is also called Purple Back Choi, Blood Skin Choi, Guanyin Amaranth, Two-color Sanguine Grass, Red Phoenix Choi, Sky Green Earth Red, Red Back Choi, Red Jade Choi, the scientific name is Purple Back Anemone, which is a perennial herb that belongs to the genus Tuscan in the family of Asteraceae. To harvest perennially, planting techniques and management methods are important.
A, cultivate strong seedlings, you can choose the former crop propagation and seed propagation
Blood Bichromicum although flowering but seldom fruit, because its stem nodes are easy to produce adventitious roots, in the insertion of strips is easy to survive, so most of the current cuttings propagation seedlings. The use of cavity trays, nutrient pots, seedbeds in the previous crop are possible.
Seed propagation is generally carried out in the spring, when the temperature stabilizes above 12 ℃ can start sowing, the recommendation is to open the furrow strip seeding. Pay attention to the spacing between the rows of plants, and timely inter-seedling after seedling. Seedlings can emerge in 10 days after sowing, and can be transplanted to the field when they have 5 to 6 true leaves. When the seedlings grow to adulthood, they can be used as virus-free mother plants for asexual reproduction.
Two, land selection, land preparation, base fertilizer, make beds, planting
While the soil requirements are not strict, but if it is artificial cultivation of its growing period is relatively long, the amount of fertilizer and water required will not be less, in order to obtain high-quality high-yield, it is appropriate to choose a deep layer of loose soil, rich in organic matter, well-drained, water retention and fertilizer retention capacity of a relatively strong, well-aerated micro-fertilized soil. In order to get a good yield, it is suitable to choose a deep and loose soil, rich in organic matter, well-drained, water retention and fertilizer retention capacity is relatively strong, good aeration slightly acidic sandy loam. To combine with deep plowing to the base fertilizer, it is recommended that you apply 3000 to 5000 kilograms of rotted farmyard manure per acre, and with the appropriate amount of phosphorus and potash fertilizer is 10 kilograms each, or choose the three elements of composite fertilizer 25 kilograms, the ground turned evenly leveled to make a flat bed.
The planting period of open field cultivation is selected in the spring after the late frost, if it is greenhouse cultivation in all seasons, but it is best to choose in August, so that after the winter can be harvested to meet market demand. When planting the density size needs to be based on the geotechnical, the length of the growing period to decide, when the soil is fertile when you can plant appropriate thin some, if it is thin soil can be appropriate dense planting. Growing period is relatively long appropriate thin some, growing period is relatively short, or want to improve the yield of the early stage can be slightly dense. Watering enough planting water, wait until the water seeped down in time to seal the soil.
Three, field management
In the winter pay attention to warmth, pay attention to the shed temperature to maintain above 10 ℃. Covered with straw thatch at night, to the summer to shade and cooling, to control the temperature at 20 to 25 ℃ is more appropriate.
In the blood bikini cabbage throughout the growth period to pay attention to maintain a moderate degree of moisture, the recommendation is to see dry watering once? Full water? , pay attention to drainage and flood prevention in the rainy season. In the plant before sealing the ridge must be timely weeding, harvesting period requires a small number of times to fertilize, every harvest after 2 times you need to apply urea with water per mu is 10 to 15 kilograms. If after harvesting many times pay attention to the timely removal of the base of the old leaves, which can promote ventilation and light, is conducive to the emergence of new shoots, but also will extend the harvesting period to improve the blood of the vegetable yield.
At the same time to do a good job of pest control, timely harvesting.
The above selection of good varieties, the correct propagation methods, proper field management are all the blood Bibb planting is the need to pay attention to the technology.
