The hebei vegetables ssis-617, a high-quality variety that has been promoted in recent years, has become a “rich flower” for vegetable farmers in the north china region by virtue of its disease-resistant, high-yielding and high taste. However, their cultivation techniques are stringent and minor imprudent may lead to reduced production or lower quality. This paper will take into account the experience of the hebei multi-field vegetable farmers and reveal the five core planting points of the species, which will help you to achieve a high yield
I. Soil preparation: building a high productive base
Vegetables are more demanding for soil, and ssis-617 requires more fertile, loose and well drained plots. Pre-planting requires deep cultivation of 25-30 cm, combining 5,000 kg of corroded organic fertilizer (e. G., chicken dung or cow dung) and 15 kg of potassium sulphate compound fertilizer per acre to enhance soil fertility. If the soil is adhesive, it may be mixed into a slurry or sand to improve air permeability. It is noteworthy that front crops should avoid cross-flower vegetables (e. G. Cabbage, kale) to reduce the risk of endemic diseases。
Pettyr: new shed cultivation proposes high-temperature silt, 15-30 days of corrosive sealing, effective fungicide and increased earth power by mixing straw with fungus enzymes。
Seeding seedlings: time and detail
1. Seeding time: spring in the hebei region is suitable for late march to early april (at temperatures above 8°c) and autumn to early august. Premature exposure to high temperatures leads to bulkballs, with small flower balls and low yields later。
Seed treatment: 30-40°c for spring planting the hot water is impregnated for two to three hours and sprouts are sprung up to lumber and seeded live in the autumn, provided that it is impregnated with ammonium dysen or agro-chainin。
3. Cultivation management: cultivation is done by means of nutrients or caves, the base of which is made of grass-grass carbon: cylindrium = 2:1 and is added to the spermic acid. Shrimp periods are maintained at 20-25°c during the day and 10-15°c during the night, in order to avoid being long。
Planting and field management: water fertilization is key
Plantation density: 2,000-2500 units per acre (50-60 cm range) in spring and 1800-2000 units in autumn (70 cm range) to ensure ventilation。
2. Fertilizer strategy:
Shrimp period: 7 days after planting, pursuit of rare dung root, 500 kg per acre。
Lotus term: 10-15 days of water control, 10 kg of urea per acre, promoting foliage。
Plumbing season: when the ball is 2-3 cm in diameter, 20 kg of potassium compound fattening per acre and soil moisting, using ditch irrigation to avoid the accumulation of water roots。
Key points: during the booming season, one or two outer leaf coverings are to be broken to prevent direct sunlight from causing yellowing, and new leaves are to be replaced with atrophy in time。
Iv. Pest and pest control: integration of biological and chemical methods
Ssis-617 is highly resistant to disease, but remains vigilant:
- patients: 72 per cent can be sprayed with 600 grams of liquefie; soft rote can be ploughed with agrococin。
Insects: vegetable moths and larvae are given priority biological control by avimin or bacillus souyun (bt emulsifier), and aphids are lured or sprayed with cedar。
Note: discontinuation of chemical pesticides 15 days before harvest to ensure non-hazardous quality。
Collection and preservation: locking in the best yield period
When the ball is 10-15 cm in diameter (early ripening) or 25-30 cm in diameter (medium and late ripening), it is collected in a timely manner when the surface is tight and the edges are not loose. Two to three small leaves to protect the florist from mechanical damage。
Scrutinizing techniques: fast pre-colding after harvest, wrapped in wet towels or in a freezer at 0-2°c, with an extended shelf life of more than 20 days。
While the cultivation of the hebei vegetable ssis-617 requires careful management, the scientific planning of soil, water fertilizers, pest control and so forth has also allowed ordinary farmers to achieve a high yield of 3,000 - 4,000 kg of acre. Following the technical points and adapting to local climate flexibility, this "silver ball" is bound to be a beautiful landscape for rural renewal
