I. General description of the blue
Slurry, which is a cross-flower vegetable, has a unique taste, a fresh fragrance, a rich nutrient and contains a variety of nutrients, including proteins, fats, sugars, carbohydrates, calcium, phosphorus, iron and vitamins. Cultivation is increasingly receiving attention in modern societies, with broad market prospects and widespread application to agricultural production, along with high nutritional and pharmaceutical values。
Ii. Blue growing techniques
Land selection
The blues prefer soil that is deep, lax and fertile, well drained, fertile, acidic or neutral, and where there is sufficient sunlight, temperatures are wet and rainfall is good. However, the requirements for soil are not stringent, except for saline and very low fertility soils, which are not suitable for cultivation。
Varieties selection
At present, there is a wide variety of blues, common in tomatoes, round blues, square blues, etc. We should select seeds in accordance with local climate, soil and other factors, and should be characterized by colour, taste and tolerance。
Reproduction methods
The most common breeding methods are seed breeding and adhesion breeding。
(1) seed reproduction
Use should be made with care to shorten the planting cycle and ensure reproductive effectiveness. When the average temperature is 15-26°c, seedlings are sowed by night rain or by artificial irrigation, so that the temperature and humidity are controlled during the seeding period and it is not appropriate to transfer them prematurely。
(2) cultivation
In high-temperature seasons, the gill blues used to breed are relatively fast and the fruit is of better quality. The usual method of embroiling is that of a side branch for july-august. After disinfection, they are inserted into the breeding soil of the temperature-moisture environment. Before planting, care should be taken to strengthen management and promote good growth of the trees。
Plantation methods
Pre-processed and pacified land, 15 cm deep, 50 cm long, 15 to 20 cm deep, and 0. 7 to 1. 0 cm deep. 2-3 grains per den, covered in soil。
Management techniques
(1) cultivation of pine land: land with low levels of deep-earthing and shallow layers of soil can be cultivated through mechanical and manual means to increase soil permeability and fertility。
(2) preserve: the need for water is high in the blues and good water should be maintained. There is a need for sufficient water during periods of expansion and in case of fertilisation。
(3) fertilisation: a fertilizer application is carried out approximately 10-15 days after seeding, and a second application is carried out when the tubing stretches 20-30 cm。
(4) weed removal: weed removal in a timely manner during growth, keeping the ground clean and preventing nutrients from being looted by weeds。
Pest control
Insects such as larvae and fungi diseases such as black rot, disease and disease are more affected. Prevention of pests and diseases can be controlled by chemical pesticide spraying or biological control。
Iii. Elective efficient enforcement of ground
Blue has a variety of effects, including appetite, beauty, spleen stomachs and anti-age. In terms of nutritional value, slurry is a low-calorie, high-fibre, high-protein vegetable, containing various nutrients, such as 2g protein, 0. 5g fat, 2. 9g carbohydrates, 2. 4g cellulose, vitamin c 30mg and 1. 8mg iron, for every 100 grams。
Market prospects
Demand in the blue market has been growing year by year, with wholesale markets, supermarkets, green cars, etc. Being the most common market outlets. Prices are stable, markets are promising, and scale production and processing sales are evolving, and future market demand is expected to expand。
Conclusion
Blue is a nutritious, fragrance-rich vegetable whose planting techniques are simple, manageable and adaptable. When planting slurry, attention should be paid to the selection of land, the selection of varieties, the selection of breeding methods and planting methods, together with management techniques to ensure its production and quality. In the future, as people's demand for nutritional health increases, the blue market demand will continue its trend of steady growth。
