Kale cultivation techniques and maintenance management, say which?

Raising collard greens, to buy collard greens seed planting to appreciate the best effect, but most of the flower seed agents minimum package is more than a hundred, ten eight seeds can not be purchased. Many enthusiasts can only directly buy manufactured collard greens potted flowers from the flower market to appreciate, this can save a lot of inconvenience though. Specific details are as follows:

a. Adaptation to solarium

Collard greens like wet and cold, after several short-term frost has not yet wilted, seeds can germinate at 3-5 ℃, suitable for the development of ambient temperatures of 18-25 ℃, able to withstand sustained high temperatures of more than 35 ℃. This is a long sunshine plant, the nutrient growth period is long, sunshine, high light intensity, beneficial to leaf stem growth and development. Kale prefers moisture and does not tolerate drought, the suitable soil moisture content of 75-80% and relative humidity of 80-90% are specified. Kale on the soil environment standards are not harsh, but still to contain organic matter soil or sandy loam is most suitable for the neutralized soil layer.

Kale cultivation period is long, several picking, fertilization is relatively large, cultivation should be based on the base fertilizer as the leading, and with phosphorus, potassium fertilizer. In general, collard greens are resistant to low temperature and heat, like moisture and fertilizer, can be manufactured in the solar greenhouse anniversary production. However, in view of the persistent high temperature, drought, strong light can enhance the dietary fiber content of the goods, reduce the quality of the equipment. Thus kale is especially in suitable for fall and winter, spring and winter solarium cultivation. Kale adaptability, cultivation management is easy, the key to the text details kale solarium fall and winter cultivation technology.

Two, commonly used varieties

1, Apeida: introduced from the Netherlands, a generation of mixed hybrid varieties, the strain of the ordinary high and medium, the leaves dark blue, the leaf edge of the curl degree is large, the appearance of the rich and tidy. The quality of tender, good taste, commodities after production can still maintain the bright green and unique flavor. This variety of drought resistance, both for spring, dew cold cultivation, but also for winter solarium cultivation.

2, Worcester: introduced from the U.S. varieties, the strain common high medium, abundant growth and development. Leaves dark green, leaf edge finely divided and rolled. Taking leaves bright green, soft material, stronger flavor. Resistant to low temperature, high temperature, fertilizer, storage, moss late, long harvest period. From sowing to obtain need about 55 days. Can be spring and fall open field cultivation cultivation, can also be winter solarium cultivation. After spring plowing, if the management is appropriate, can continue to pick to winter, the production is higher. Suitable for fresh and production and processing.

3, Wintebo: introduced from the Netherlands, a generation of mixed-seed hybrids, plant general high and medium, abundant growth and development. Leaf color dark green, leaf edge rolled into folds. This variety of frost tolerance work ability is very strong, in the Yangtze River section can be cultivated in the winter open field cultivation cultivation, winter and spring to obtain. In Jiangsu, Zhejiang and Shanghai areas, northeast of the middle and south, can be used to improve the sun bed or sunshine greenhouse winter cultivation.

Three, cultivate strong seedlings

1, sowing period: generally in early to mid-August sowing, seedling age 30 days. Sowing too early, the temperature is high, the growth and development of seedlings is not good; sowing too late, the harvest period is too short, jeopardizing production.

2, sowing method: in the plastic seeding tray or the production of wooden boxes, loaded with 4 parts of composted horse manure, 5 parts of fine soil, 1 part of the manure surface configuration of the culture of the soil, watered thoroughly, each square meter sowing or strip seed 10 grams up and down, covered with fine soil about 1 centimeter (1 flat finger). After filling the soil cover tightly a layer of newspapers and other moisturizing and hydrating things, but the seedlings for the soil must be removed immediately after the moisturizing and hydrating things.

3, seedling management: maintain a higher temperature and soil moisture content before the emergence of seedlings is beneficial to promote the emergence of seedlings, daytime 25 ℃ or more, 15 ℃ or more in the evening. Seedling moderately reduce the temperature after draining water to prevent exuberant growth, between the opening of clusters of seedlings, replenishment of seedlings after sprinkling water to stabilize the seedling. Occur 1-2 leaves when seedlings plastic cup seedlings, paper bowl or nutrients in the upper side, single nutrients should ensure that the total area of 6cm thick as above. Seedling leaf spraying 0.2% potassium dihydrogen phosphate aqueous solution 1-2 times, to facilitate the strengthening of seedlings. Immediately remove seedlings, pour seedlings 1-2 times. Properly drained before transplanting to reduce the temperature, strengthen the body, and enhance the resistance of the seedlings.
