Coriander, also known as wolfberry, is a herbaceous plant of the first and second year. Its stems and leaves contain abundant nutrients and have special flavors. They are seasoned vegetables. Parsley is a long-day crop, long-day sunshine of more than 12 hours can promote development," in the short-day conditions, the lower temperature below 13 °C can be twitching and flowering, the adaptability of coriander strong, the period of vegetative growth of plants It is possible to survive the intense summer heat and to withstand severe cold for a long period of time under simple conditions of coverage. Therefore, it can be cultivated throughout the growing season in China, but the cultivation in autumn with relatively low sunshine and low temperature is high in yield and quality. Appropriate temperature during growth is 17-20°C, and can tolerate low temperatures of below 8-10°C in a short time. At low temperature, the color of its leaves and petiole turns purple, and normal growth can be resumed after temperature rise, so it is This kind of vegetable with strong cold resistance is suitable for cultivating and cultivating early spring in the open field, and is harvested around June 1. It is a kind of cultivation technology that regulates the production of the greenhouse and the open field production. Its technical points are as follows:
1. Soil fertility selection: shady, loose soil, fertile, sandy loam rich in organic matter content, deep tillage and drying, the depth of the ground is generally about 25-30 centimeters, combined with the application of 5000 kg of farmyard fertilizer, preferably in the fall.畦 畦 畦 畦 畦 畦 畦 畦 畦 畦 畦 畦 畦.
2, soaking before sowing germination early spring on April 5th 10th, the seeds first soaked with water for a day and night, and then remove the control of clean water, semi-humidity is not suitable for the state. When germinating, the seeds should be packed in plastic pots. Do not cover the pots for convenient ventilation. Place in the indoor shade at room temperature (20°C) and at least twice a day during germination, otherwise it will be easy to shoot dry. After 7-10 days, the buds can be released.
3, timely planting coriander buds neat, sow on April 15-20, sowing with seedlings, mu seed 5 kg, require sowing water before sowing, after sowing with rammed soil cover tight, cover the agricultural film.
4, the management of plastic film When the temperature exceeds 15 °C, strong light, 8 o'clock in the morning to open, 3 o'clock in the afternoon and then on the agricultural film. Prevent roast seed roast seedlings.
5, watering parsley production season low temperature, if the water too much work, it will reduce the temperature, affect plant growth, the principle is not drought, not pouring, less pre-cast, late slightly more. Keep the soil moist.
6, top dressing is best not to top-dressing, if the base fertilizer is insufficient can be outside the harvest 10 days before the root dressing. Spray urea at a concentration of 1.5% and spray twice.
7, timely harvest parsley from sowing to harvest takes about 50-60 days, generally May 25-June 5 harvest. The per mu output can be up to 1250 kg, and the price is good, high yield and high efficiency.
