After the beginning of autumn, parsley was planted in the open season. Coriander: Current Management Focuses on "Three Preventions"
Anti-flavoured parsley planted in summer and autumn, although not convulsed by low temperature during seedling stage, it will twitch due to long days (conditions) in summer and autumn. This requires the selection of cildro-resistant coriander varieties in production. In addition, to strengthen the management of fertilizer and water (the whole parsley should be poured in small water spray vegetables 5 to 7 times, the first three water, every 10 days or so watering and spraying vegetables Zhuangshouling once, from the fourth water from every 6 ~ 7 days watering spraying vegetables Zhuangshouling once.Topping water, light recovery to raise seedling fertilizer, apply urea about 10 kilograms per acre, after each pouring 2 to 3 times water urea recovery, 10 to 12.5 kilograms per acre), Spraying 800 times the new high fat film once can reduce the occurrence of convulsions.
Prevention of "red stalk" Coriander "red stalk", that is, the stem and leaf portion of parsley from green to red, reducing the commercial value of parsley, the purchase price by half. During the summer and autumn, the parsley planted in the open season is exposed to strong light and turns red, especially when the seedlings are too late (plant height exceeds 8 cm). To prevent the emergence of "red stalks" in the parsley crop, first, seedlings in the morning should be used to spray a new high fat film once. In production, seedlings should be grown to a height of 3 cm in height, and the spacing between the seedlings should be kept at 2 cm. Left and right; the second is to cover the shade net, and the qualified farmers can take 80-100 cm of scaffolds after sowing. The shed is covered with a shade net.
Anti-rainwater In summer and autumn, there is a lot of rain, which is very harmful to the coriander seedlings just after emergence. After the heavy rain, it suddenly turned green and could easily lead to rotten parsley. After the rain, then gently pour the well water, the amount is not to submerge the seedlings is appropriate, spray a new high-fat film once, can prevent rotten coriander.
During the three defenses, the timely use of vegetables, Zhuangshuling, and new high-fat membranes can make the stem thick, thick leaves, fresh leaves, plants, and natural taste. At the same time, it can increase the ability to resist disasters, reduce the amount of pesticides and fertilizers, and reduce residual poisons.
