Water celery planting method steps are as follows:
The first step of crop stubble area selection
Generally choose the soil is fertile, good performance of fertilizer and water retention, easy drainage and irrigation of shallow water lotus root fields, spring corn fields, early soybean fields and other stubble areas.
The second step of fertilizer preparation and sowing
7, 10 days before sowing, per mu of high-quality organic fertilizer 2000, 2500 kg or cake fertilizer 100, 150 kg or more, and then deep plowing on the water composting, the more plowing, the deeper the turn over, composting the longer, the easier it is to get high yield. In the last plowing and land preparation, mu applied three yuan compound fertilizer 50-75 kg or more to achieve a level field surface. Build around high ridges (height of 50 centimeters or more) and irrigate with a thin water layer.
The third step in the selection of seed germination
Mid to late August, celery stems shall be bundled with straw. Each bundle should be 2-3 rows, 20-30 cm thick. After tying, lay the plants horizontally one layer of stems and vertically one layer, cross-stacked in the shade of the sun or on the roof of the north wall, covered with straw or other aquatic plants, and when there are no natural conditions, shade nets can be used. Water once before 9 a.m. and once after 4 p.m. to retain moisture and prevent fever. Under cool, ventilated and humid conditions, grow 1-2 cm shoots in the axils of each node in about 7 days. At the same time rooting takes place. The stems thus germinated and rooted can be sown, and loose shakes can be cut to a growth extent of about 30-40 cm. The row of seeds can generally be cut to about 60 centimeters.
The fourth step of shallow water measurement row of seeds
Watercress suitable sowing period in early September, too late is not conducive to high yield, in order to achieve high yield, row is the basis of the buds, after the buds can be row of seed stems, row of law is that the buds of the buds, the end of the stems towards the ridge, the tip of the tip of the field, buds face up. The following points should be noted when planting: first, in order to ensure the density, the planting spacing is usually 6-8cm; the general planting amount per mu is 200-250 kilograms. Secondly, the surface of the field should be flat in order to promote the growth of buds and roots for consistent growth. At this stage, it is most important to avoid uneven field surface, highly arid, unfavorable root system and bud growth; when the water is shallow, the sun is hot, and the buds are hot when the water is shallow, to grow into seedlings, the water layer gradually deepens.
The fifth step according to pest control
When the seedlings grow to 2-3 leaves, start fertilizer, to promote the plant as soon as possible to grow strong, every 7-10 days after fertilizer, with urea 10-15 kg per mu. If aphids are found, use net spray or deep water (about 4 hours) to control aphids.
The sixth step of water management
Celery can be drained from the field after complete root growth, put once, and then the water layer gradually deepened, the initial 5-10 cm. Later water layer in about 30 cm, keep the plant surface about 15 cm, after winter, water celery stop growing, mainly to irrigation to keep warm and prevent freezing.
Seventh step seedlings buried deep
When the seedlings up to 25 cm or so, combined with weeding and fertilizer mixing, the large field to rectify the ground, one is to move dense fill sparse, so that the distribution of the field is uniform; the second is the high lifting low, so that the growth of the field group is neat and tall. At the same time, y buried watercress can be used to soften and improve the quality of watercress.
The above is about the planting method of watercress, I hope it can help you.
