Water spinach, also known as water spinach, is a vine plant of the Convolvulaceae family and sweet potato. It is grown in various regions of my country because of its delicious taste and rich nutritional value, as well as its strong adaptability. However, there are The yield of some growers is not high, so how can they grow water spinach with high yield? How to harvest it?
1. How to grow water spinach with high yield?
1. Planting method
Water spinach usually starts sowing around April. Many people think that it is enough to fertilize the soil before sowing. This is not the case. The soil needs to be plowed twice before planting. Every time, you need to plow deeply and sprinkle enough fertilizer and water. This is called nourishing the soil, because water spinach prefers a fertile and watery environment. This can satisfy its nutrients to the greatest extent. Whether it is transplanted or inserted into a pole, do not plant it too deep. It should be about 4 centimeters into the soil. It is best for water spinach to take root and develop. Because it grows quickly, fertilizers must keep up. It is generally best to use nitrogen fertilizer.
2. Field management
Because water spinach is a multi-harvest vegetable, it grows quickly. Sufficient light and abundant fertilizer and water can ensure its growth. Generally, the amount of top dressing after planting should be small. Three weeks later, top-dress fertilizer again during the growth period. The amount should be relatively large to ensure good growth. After each harvest, the soil can be loosened appropriately. This is called root nourishing. Of course, the fertilizer cannot be less. It is better to add bio-fertilizer if conditions permit. .
3. Precautions
Due to its fertilizing characteristics, water spinach is destined to grow weeds quickly, so pay attention to clearing them. Secondly, if the water spinach in an area does not grow well, then Remove some because they are too dense. If you find rotten or yellowed leaves, take them away as soon as possible. Do not leave them in the field where they are prone to infection. When pests are discovered, try to remove the entire plant because the pests are too contagious.
2. How to harvest water spinach?
Timely harvesting of water spinach is the key to its high yield, so when is the best time to harvest water spinach? Generally, water spinach propagated by seeds must wait until the seedlings grow to about 35 cm before harvesting. If propagated by cuttings, you need to wait until the newly grown canes grow to about 35 cm before harvesting. This is There are no specific regulations on when to harvest water spinach, but what you need to remember is that the best time to harvest is when water spinach grows to 30-40 centimeters. How long it takes to harvest water spinach actually depends on the growth speed of water spinach itself. It is decided, so if you want to increase the yield of water spinach, you need to increase the growth rate of water spinach.
There are actually two ways to harvest water spinach. The simplest one is to harvest it all at once, which is to uproot the water spinach when it grows to about 30-40 cm. If you harvest water spinach in this way, The yield is relatively low. The yield of one acre of planting is about 3,000 kilograms. The second method is to harvest multiple times in batches. That is to say, when the water spinach first grows to 30-40 cm, the tender Pick the buds, keep the underground and a small part of the above-ground stems and leaves, and apply top dressing once. This can promote the water spinach to grow again and be used multiple times. In this way, at least 10,000 kilograms of water spinach can be produced per acre, and when harvesting in batches Reasonable thinning of branches and leaves should be carried out to prevent premature plant failure.
Summary: The above is the relevant introduction to the high-yield planting and harvesting of water spinach. Growers can refer to the above methods for planting and harvesting. I hope it will be helpful to friends in need!
