Parsley is a high-grade vegetable, which is rich in vitamins, has a rich aromatic odor, and has a high nutritional value. In addition, there are various medical values ​​such as lowering blood pressure, iron supplementation, tranquilizing the nerves, treating constipation, and preventing bowel cancer. The use of protective cultivation of parsley can achieve annual production throughout the year. In the early spring, the output of parsley is 3,500 kilograms, and the yield of mu is generally around 10,000 yuan. The planting benefit is considerable. Its cultivation techniques are as follows:
1. Choose the best kind. According to market demand, targeted selection of suitable varieties. In the production, imported varieties with high yield, excellent quality and strong disease resistance should be selected, such as Japanese parsley, French parsley, Danish parsley and other varieties.
2. timely nursery. The sowing time is in early February and nursed in a greenhouse. Use fertile garden soil and fully decomposed manure in a ratio of 2:1, add 1 kg of compound fertilizer per square meter, and mix fertilizer and soil and spread it on a seedbed with a thickness of 10 cm. Use carbendazim and thiram Wet powder for bed soil disinfection. The foot water was poured first, and the water was covered with fine soil after seepage. The seeds were evenly spread on the bed surface. The fine soil after being covered with the disinfection was 0.5 cm thick. Generally, the seed amount per mu was about 75 grams.
3. Soil preparation. Parsley has a large demand for nitrogen fertilizer. The base fertilizer should be applied to a sufficient maturity of 5,000 kg of farmyard manure or 3 m3 of mature chicken manure per acre, and a total of 45% of high-nitrogen and low-phosphorus high-potassium compound fertilizer with a total content of 75 kg, 1 kg of biological fertilizer and fertilizer. Distribute evenly on the sash surface, then plow till it is leveled.
4. Timely colonization. Planted around the end of March and planted when the seedlings had 5 to 6 true leaves. Select a continuous high temperature and high temperature for a week, planting, spacing 20 cm, spacing 15 cm, acres planted 15,000 to 18,000 plants, planted immediately after planting water.
5. Field management. Within 3 days after planting, the temperature in the shed during the day was kept at about 23°C, and the temperature at night was not lower than 15°C, which was conducive to promoting rapid easing of seedlings. One week later, parsley will grow a new root system and end the seedling period. In the early stage of growth, the outside temperature is relatively low, and it is necessary to diligently cultivate the soil to increase the temperature of the ground and promote the growth of roots, stems and leaves. When the plant height is about 20 centimeters, it enters a period of prosperous growth and sufficient water and fertilizer supply must be ensured. In general, 20 mu of urea or 15 kg of nitrogen and potassium fertilizers are applied with water, and fertilizer is continuously applied twice. In the later period, the combination of sprayed protective fungicides to increase foliar micronutrients can improve quality, increase yield, and increase yield.
6. Timely harvest. In the early spring, the shelter cultivation of the greenhouse is generally about 45 days after planting, and the plant height can be harvested when the plant height reaches 40 cm. Two days before harvest, a small amount of water was poured, moisten the noodles, and the roots were uprooted. The old leaves and the diseased plants were removed. Each 1 kg was tied into a bundle and stored in a plastic bag and then sold on the market.
