Does the hollow cabbage grow longer after cutting a crop

Hollow cabbage can be harvested and regenerated, and belongs to the multi harvest vegetable category. The regeneration ability of water spinach is mainly related to factors such as variety characteristics, water and fertilizer management, and harvesting methods.

The stem nodes of water spinach have strong sprouting ability. It is recommended to reserve 1-2 nodes at the base for harvesting, and with sufficient water and nitrogen fertilizer supplementation, new shoots can usually grow in 7-10 days. In a warm and humid environment, it can be harvested 5-8 times a year. Choosing cutting resistant varieties such as white stem water spinach and harvesting them with sharp cutting tools at oblique angles can significantly improve regeneration efficiency by avoiding pulling and damaging the root system. Timely application of decomposed organic fertilizer or quick acting nitrogen fertilizer after each harvest to maintain soil moisture at around 70% is beneficial for promoting new shoot germination and leaf thickening. When there is continuous compaction of soil, invasion of pests and diseases, or low temperature and drought, the regeneration ability will significantly decrease. When the stem becomes woody, the root system ages, or infected with root rot disease, the new shoots sprout slowly and the quality deteriorates. At this time, it is recommended to remove the entire plant and replant. If harvesting too frequently during the high temperature period in summer leads to plant weakness, it may result in only growing stems without leaves. Harvesting should be suspended and shading and moisturizing should be strengthened.

When planting water spinach, it is advisable to choose loose and fertile soil, with the main base fertilizer being composted farmyard manure. During the growth period, the bed surface should be kept moist but without standing water. During the harvest interval, potassium dihydrogen phosphate solution can be sprayed to enhance stress resistance and timely prevent and control leaf eating pests such as Spodoptera litura. Avoid continuous cropping with Convolvulaceae crops such as sweet potatoes during crop rotation to reduce the harm of root knot nematodes. It is recommended to use containers with a depth of more than 30 centimeters for home potted plants, and replenish new nutrient soil after harvesting 2-3 times.
