Detailed Explanation of Key Techniques for Growing Red-Skinned Radish in Greenhouses
Red-skinned radish is the common red radish we see in daily life, and it has a cultivation history of over a thousand years in China. Red radish is currently quite popular on the market, and its planting area is also relatively large. There are many ways to grow red radish, such as open-field cultivation and greenhouse planting. The more common one is greenhouse planting. So how should greenhouse red radish be grown? Below, the editor will give everyone a brief introduction. Let's take a look together!
1. Planting Time
Red radish is generally planted in summer, and sowing can be done from May to August. The planting time should mainly be adjusted reasonably according to the growing region. For example, when planting in the Yangtze River basin, the planting time is generally from June to July. Red-skinned radish is an early-maturing radish variety, with a growth period of about 45 days. Its adaptability, moisture tolerance, and disease resistance are all relatively strong, and its yield is also relatively high. Before planting, we must first apply sufficient base fertilizer. Doing a good job with water and fertilizer management is the only way to ensure the normal growth of red radish and increase yield.
2. Land Selection and Land Preparation
Before planting, we also need to do a good job in selecting the planting plot, ensuring that the soil layer is thick and soft, drainage and irrigation are normal, and fertility is sufficient, with sandy soil as the main type. Then do a good job in land preparation, remove the residues of the previous crop and weeds left on the soil, deeply plow the soil, and harrow the field. When preparing the land, we should also apply an appropriate amount of base fertilizer. With farmyard manure as the main type, apply about 1200 kg per mu, and mix it fully with the soil. Then select varieties with strong disease resistance, high yield, and lodging resistance for planting.
3. Timely Planting
The planting method for red radish is generally based on mixed planting, and the mixed planting variety can be potato. Plant potatoes according to the spring planting method, with a sowing rate of about 2 kg per mu. The sowing method can be mainly broadcast sowing or hill sowing. After sowing, level the ground, then retain planting rows, with one composite strip about every two meters. Plant red radish and potatoes separately. When sowing red radish, be sure to control the plant and row spacing well. After land preparation, directly scatter the seeds into the ground, then rake them level appropriately. Seedlings can also be raised for transplanting.
4. Field Management
During the seedling stage of red radish, we should do a good job in thinning and final singling according to the growth of the seedlings and soil fertility, and reasonably adjust the planting density. Then apply an appropriate amount of urea topdressing to enhance the growth ability of the seedlings. During the bolting and flowering stage, attention should be paid to appropriately increasing the amount of watering and fertilizing to improve the flowering and pod-setting rate of red radish. Then there is the need to do a good job in pest and disease control. We should pay attention to frequently observing the growth of red radish, and after discovering abnormal conditions, take corresponding measures in time to reduce losses.
The above is a brief introduction to greenhouse cultivation techniques for red-skinned radish. When about 80% of the red radishes have matured, harvesting can begin. It should be carried out on sunny days, which can improve the storage capacity of red radish. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
