How is the management of Alisma orientalis planted after it is planted? Alisma is a kind of clear water plant, which is also very fond of fertilizer during the growth process. If the plant is not managed after planting, it will definitely bring a lot of trouble to the later production. Then let's take a look at the management measures after the colonization of Alisma plants.
First, the support of seedlings after the planting of Alisma orientalis
Within 2-3 days after the planting of Alisma, it is necessary to carefully and carefully check the seedlings in the field of Alisma, and if it is found that there are floating seedlings or blown down by the wind, it should be immediately stabilized and stabilized. If there are missing seedlings, the seedlings should be filled in time. Guarantee the whole seedling. At the same time, it is found that weak seedlings or diseased seedlings with poor growth should be removed in time to make up the growing and healthy seedlings.
Second, the cultivating weeding and topdressing after the planting of Alisma orientalis
Alisma is more fertile, and its growth period is relatively short, so the key management of high yield is that the time of topdressing is early or late. The ploughing, weeding and topdressing of Alisma can be carried out continuously in the same period of time. It is advisable to fertilize and then weed and weed, usually 3-4 times. The topdressing should be early, and the concentration should be concentrated within two and a half months after transplanting. Be sure to grasp the principle of fertilization. If the leaves of Alisma are not soft but very hard, and still stand upright, then this performance means that the diarrhea at this time is relatively lack of fertilizer. Fertilization generally applies 1000-1500kg/mu of animal manure per application, but it is necessary to clear the water in the field before application. The third and fourth fertilization is the key. Phosphorus and potassium fertilizer should be added to promote the expansion of bulbs. In the fourth fertilization, the fertilizer of grass ash can be increased. The amount used is about 100kg/mu. After each fertilization, ploughing and weeding are carried out.
3. Irrigation and drainage after the planting of Alisma
Alisma is a water-reducing plant that has different requirements for the depth of irrigation during different developmental stages. After the transplanting of Alisma orientalis, it is more appropriate to keep the water in the field at a depth of about 3 cm. After the second ploughing of Alisma, the aboveground part is vigorously growing, requiring more water, and the depth of the water can be further 1-2 cm deep. After the third cultivating, enter the tuber expansion stage, the field water should be reduced, and the field should be “flowered and water surface†and drained before the winter.
4. Picking buds and removing moss after planting
After the second cultivating of the Alisma orientalis, Alisma will gradually extract the flower moss and the lateral buds, and should be removed as soon as possible. When picking the moss, it should be broken from the base, leaving no residue, otherwise the lateral buds will still pick up the flower buds. Flowering flowers and seeds will cause the bulbs to be thin and small; the lateral buds will grow long, the bulges at the top of the bulbs will be more forked, the processing will be inconvenient, and the quality will be affected. Removal of flower moss and lateral buds can also ventilate and transmit light in the field, reducing pests and diseases.
The above is the introduction of some management measures after the planting of Alisma orientalis. If you have planted Alisma, you must pay attention to its field management work, or the final impact is your own harvest.
