Water celery cultivation techniques
Water celery is rich in a variety of nutrients indispensable for the human body, its output is high and stable, less pests and diseases, is pollution-free food, weather conditions have little effect, and is one of the winter plugging species, per mu yield of about 3,000 kilograms High-yielding fields can reach more than 5,000 kilograms. General mu benefits from 2000 to 3,500 yuan, eight towns of eight eight villagers Cai Youlan years of shallow water bream - water celery planting, mu production value of more than 6,000 yuan. The supply of cress is long, from late November until the second year of March. The technique of planting water celery is not complicated, as long as it has the conditions of soft soil, fertile soil, rich organic matter, convenient irrigation, and good water retention, and it seizes several key measures to stabilize production and increase production. 1. Choosing a mouthful to choose a fertile soil with good fertility and water retention performance, convenient irrigation and drainage of shallow water, spring corn fields, and early soybean fields. 2, 7-10 days before fertilization preparation, 2000- 2500 kg of high-quality organic fertilizer or 100-150 kg of cake fertilizer per acre, and then deep plowing water, the more ploughing times, the deeper, the more The longer it takes, the easier it is to get high yields. In the last ploughing and soil preparation, the Mushi three-element compound fertilizer was more than 50-75 kilograms, reaching the flatness of the field. The light was rotten. Takata was built around it (a height of 50 cm or more) and a thin layer of water was poured on it. 3. Select seed germination In the middle and late August, the stalks of celery stalks will be bundled with straw, with each bundle of 2-3 channels and crude 20-30 cm. After tying, the stems are laid horizontally and vertically. The crosses are stacked under the shade of the sun or behind the northern wall of the house. Straw or other aquatic plants are covered with them. If there are no natural conditions, shading can be used to shade them. Every day before 9 o'clock in the morning, pour water at 4 o'clock in the afternoon and keep moist to prevent fever. In cool, aerated, and humid conditions, about seven days or so, the leaves of each section grow 1-2 cm buds. At the same time take root. In this way, the germinating, rooted stems can be sown, and they can be cut into 30-40 cm in length. The seed can be cut into about 60 centimeters. 4. The suitable sowing date for shallow water drainage water celery is in early September. It is unfavorable for high yield. If you want to seize high yield, the seed is the basis, the germination of the stems can be seeded, and the seeding method is that the germination will be The stems of the stems are toward the field ridges, the tip ends toward the middle of the field, and the buds head upwards. The following points should also be taken into consideration when planting seedlings: First, the density should be ensured. The spacing between seedlings is usually between 6 and 8 centimeters; the seeding amount per mu is generally between 200 and 250 kilograms. The second is that the field surface should be smooth in order to facilitate the growth of buds so as to achieve consistent growth. At this stage, the highest level of sloping fields is uneven, with high drought, unfavorable roots and long shoots; low water, hot sun and hot water to scald the buds, and gradually deepen the water layer after the seedlings grow. 5, topdressing pests in the seedlings grow to 2-3 leaves, began to topdressing, promote the plant as soon as possible prosperous, after every 7-10 days topdressing once, each time with 10-15 kg of urea per acre. The locusts were found and promptly sprayed or sprayed with deep water (about 4 hours). 6, the water layer management after the seedlings to be treated with water celery root growth can be drained, gently put a time, later to gradually deepen the water layer, the initial 5-10 cm. After the water layer was 30 cm, the plant was exposed to the surface of 15 cm. After entering the winter, the water celery plant stopped growing, and the water was kept warm to prevent freezing. 7, deep seedlings. When the seedlings reach 25 cm or so, weeds and composts are combined for field rearrangement. First, the fields are uniformly distributed and replenished, and the field is distributed evenly. Second, the height of the fields is raised to make the fields grow neatly, and the height is the same. At the same time, deep-buried soil can be used to soften and improve the quality of cress. Specific measures: In mid-November, plant height 25-30 cm, dig up all the planting standards with both hands, and plant them once in depth, 10-15 plants per hole. The soil depth depends on the plant height, leaving more than 10 cm above the ground. The rest was put into the mud, gradually softening and turning white under conditions of lack of light. In the deep burial, two hands and fingers spread out to hold the roots of the plant and insert the soil straightly. This requires increasing the quality of water celery, eating value, and scoring important measures in cities such as southern Jiangsu. However, it is difficult to implement this method in the field where the soil is not bad. At the same time, the output of this field will not be too high. 8, timely harvesting harvest time and standards in different regions and different, do not need to deep soften the area, in the late mid-November can be listed, through the deep softening of the listing time is postponed, while according to market demand, Listed at higher prices, especially in the New Year's Day, the Spring Festival two major festivals listed.
