Key points of cultivation techniques for autumn red peony
Qiuhongyu cultivation according to technical requirements, scientific field management, in order to high yield, the following introduces the technical points of autumn red carp cultivation:
Selection
Choose early-ripening, high-quality, high-yield "Sushu No.7", "Sushu No.8", "Yusu 303", "Xushu 18", "Zi Zi 263 (Zi Xin)", etc.; Dense, tender and tender, rich in juice, disease-free, no degradation, no adventitious roots with flat-headed seedlings; different varieties are planted separately.
Early planting
Early planting can extend the growth period of the field and increase yield and quality. For example, in the eastern part of Sichuan, the most suitable planting period for autumn red dragonfly is from late July to early August. In order to ensure maturity, it is not allowed to postpone until the beginning of autumn. It should be noted that many farmers' friends are accustomed to planting the land after the rain, and some even planted in late August, wasting a good autumn light, it is a pity.
Fertilization
In the field of light soil or sandy soil, the main ditch, furrow and furrow are opened, so that the ditch system is smooth, the ditch bottom is straight, and the rain stops and ditch. The NPK with a NPK of 15-8-16 is 25-30 kg of high-efficiency compound fertilizer, and the ridge is leveled after being evenly applied.
High ridge
There are two kinds of ridge specifications: one is ridge bottom width 1.2 meters, ridge height 40 cm, ridge surface width 70 cm, 3 rows of wrong nests per ridge (walking horse planting), nest spacing 33 cm, 5000 plants per mu, another One is that the ridge bottom is 1 meter wide, the ridge height is 33 centimeters, and the ridge surface is 60 centimeters wide. Each ridge is planted with two rows of wrong nests, and the nest is 33 centimeters. The planting is 4000 plants, the nest is 30 centimeters, and 4400 plants are planted. Also note that density corresponds to the growth habits of the variety.
Plate planting
On sunny or cloudy days, choose a strong seedling that is not affected by drought and aging. The seedlings are 30-40 cm long and 8-10 pieces of green leaves have been unfolded. It is best to have 2 to 3 5-10 cm long bases at the base of the seedlings. bud. When planting, first use a small "grey knife" or "grey scorpion" to open the nest, then the red sapling seedlings into a ring shape, into the soil 10-13 cm deep, 6-7 knots, the soil part should be flat, cover the soil In fact, it is loose, revealing all the leaves and the tip of the seedlings, and immediately penetrates the human and animal manure to stabilize the tree. In case of soil drought, you can first open the pond and fill it with water, and then harvest it after harvesting. If it is high temperature and strong light, you can use straw to cover the night for 2 to 3 days, or when planting, only the top three leaves of the seedling tip are exposed, and the remaining leaves are buried in the soil. Eli full seedlings survive. The main points are: long-tailed vines, flat-panels, and burying leaves.
Tian Guan
Topdressing seedlings: 7-10 days after planting, cultivating the pond with manure and manure 20-30, 10-15 kg of ammonium carbonate or 5 kg of urea (preferably 40% of high-efficiency compound fertilizer 7-10 kg); 100-150 kg of mixed ash with grass ash is applied to the pond between the pond and the superphosphate. It should not be applied in the pond. (The bottom fertilizer uses the high-efficiency compound fertilizer and only the human and animal manure to raise the seedlings); when the vine leaves are closed, the acre is used. 21.8% zinc sulphate 0.5 kg or compound zinc fertilizer 0.8 kg water 50 kg foliar spray; in early October, 100 g of potassium dihydrogen phosphate, 150 g of urea, and 50 kg of foliar spray 2-3 times.
The above is the key points for the cultivation of autumn red carp, which we will introduce to you.
