What are the key management techniques for asparagus lettuce after transplanting?
Asparagus lettuce is a vegetable with very high nutritional value, and its main edible parts are the root stem and leaves, etc., and it is welcomed by many people. When planting asparagus lettuce, we first need to do a good job in raising seedlings. And after asparagus lettuce seedlings are transplanted, attention should be paid to strengthening management to ensure the growth of asparagus lettuce. So how should asparagus lettuce be managed after transplanting? Today the editor will give you a brief introduction, let's take a look below!
1. Timely transplanting
Before transplanting asparagus lettuce seedlings, we first need to pay attention to selecting a good field for transplanting asparagus lettuce. The field for planting asparagus lettuce should mainly be one with strong water and fertilizer retention capacity, and before planting, attention should also be paid to applying sufficient organic fertilizer, together with an appropriate amount of compound fertilizer. Then do a good job in digging trenches and building beds, level the bed surface of the planting field, and dig the transplanting trenches. When the seedling age is about 25 days and 4-5 true leaves have grown, carry out transplanting with soil in the afternoon. When transplanting, it is generally mainly in the high-temperature season, so attention should be paid to controlling the transplanting time. Then attention should be paid to watering thoroughly to avoid damaging the roots when lifting the seedlings, and then control the plant spacing and row spacing well, and pour sufficient settling water after transplanting.
2. Fertilizer and water management
After the asparagus lettuce seedlings are transplanted, water thoroughly and cover well with a shade net. Water again after about three days, and then attention should be paid to maintaining moist soil. After the seedlings survive, uncover the shade net, and together with watering, apply an appropriate amount of compound fertilizer per mu. At the same time, attention should also be paid to doing a good job in intertillage and loosening the soil, and controlling the seedlings for about one week. When the seedlings grow to about 30 cm tall and the thickness is about 5 cm, apply an appropriate amount of urea or decomposed cake fertilizer as a topdressing. After about two weeks, together with watering, apply an appropriate amount of urea.
During the stem swelling period of asparagus lettuce, we should also pay attention to appropriately spraying chlormequat, about once every ten days. An appropriate amount of clear fresh liquid can also be used, but attention should be paid to controlling the amount of the liquid, and it should be sprayed continuously about 3 times. Avoid bolting of the seedlings, so as to increase the weight of the asparagus lettuce stem. Then during the growth period of asparagus lettuce, we should also pay attention to doing a good job in ditching and drainage, but it should not be too dry, and it should be watered appropriately. If drought occurs, then water in time to ensure the healthy growth of asparagus lettuce.
3. Pest and disease control
Pest and disease control after transplanting asparagus lettuce is also very important. Common pests and diseases in the growth of asparagus lettuce include leaf spot disease, downy mildew, and aphids, etc. When controlling pests and diseases, we should use corresponding agents for control. For example, for controlling leaf spot disease, thiophanate-methyl should be used, and for downy mildew, chlorothalonil should be used, etc. We should often inspect the growth of asparagus lettuce. When abnormal conditions are found in asparagus lettuce, the cause should be identified in time, and then corresponding measures should be taken to avoid the spread of the disease and affect the growth of asparagus lettuce.
The above is a brief introduction to how to manage asparagus lettuce after transplanting. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
