What to plant on the land planted with sweet potatoes? How to prevent underground insects when planting sweet potatoes?

After digging up the mature sweet potatoes, the soil in the field is moderately soft. It would be a pity to leave it empty and wait for crops to be planted next spring. So you can continue to plant other crops to continue to use the soil. However, you cannot choose crops randomly, such as radish, rapeseed, and spinach.

What to plant on the land planted with sweet potatoes?

radish

What crops to plant after sweet potato harvest depends on local conditions, because radish is more cold-resistant and can withstand the low temperatures in winter. Secondly, the soil in the sweet potato field is also more suitable for growing radishes, because when the sweet potatoes are harvested, the land is turned over, so the soil is loose, which is better for the growth of radishes.

When planting radishes in sweet potato fields, you can choose to sow directly. When the seedlings grow out, remove the poorly grown seedlings and leave some strong seedlings, so that they will grow faster. Some radish varieties are relatively large. When the radishes are exposed outside the soil in the later stage, they should be covered with soil in time to avoid frostbite that affects the yield.

rape

First, dig holes in the sweet potato field, then put the rapeseed seedlings in and cover the surface with some soil, and then water them. But before planting, you must first remove the weeds, and you can also sprinkle some lime powder and fungicides, so as to reduce the occurrence of diseases and pests in the later stage. But when transplanting rapeseed seedlings, you must avoid high temperature weather, and finally cloudy days. Secondly, before transplanting, you must first sprinkle an appropriate amount of water on the seedbed, avoiding too much or too little. If there is too much, all the soil will be pulled up, and too little will easily tear the roots during the transplanting process, so pay attention to the degree of watering.

spinach

Spinach is also relatively cold-resistant, so you can plant spinach after harvesting sweet potatoes. Also, before planting spinach, you should remove the weeds and mix some lime powder or disinfectant in the ground, which will be more conducive to the later growth of spinach.

Garlic sprouts

You can plant the sprouted garlic in the sweet potato field while the weather is still warm and the sweet potatoes have just been dug. But remember, you have to cover the garlic with a film, or cover it with corn stalks when you see the garlic sprouts coming out of the soil, to ensure that the garlic sprouts will not be frozen to death in winter, so that you can eat fresh garlic sprouts in the spring of next year.

How to prevent underground insects when planting sweet potatoes

Common underground pests that harm sweet potatoes include wireworms, white grubs, mole crickets, cutworms, etc.!

Agricultural control

1. Strengthen field management and deep plow the land after winter to leak out insect eggs and achieve the killing effect!

2. Use less uncomposted organic fertilizers, which contain insect eggs.

3. Set up black light to trap adult insects in the middle stage

Chemical control

1. Before planting, you can apply thiamethoxam and chlorpyrifos granules

2. In the evening of the middle season, you can spray insecticides such as thiamethoxam to kill adult beetles such as scarabs.

3. Methods for insect pest outbreaks: Directly apply poison to the roots of ticks, or spray on rainy days!

4. For cutworms and mole crickets, you can take advantage of their attraction to scent. Fry about 5 kg of bean cake, wheat bran, or corn crumbs until fragrant, then mix it with 0.15 kg of 30 times diluted 90% dichlorodiphenyltrichloroethane, add appropriate amount of water to mix until moist, and spread about 2.5 kg per mu. It is better to spread it in the windless and hot evening.

Is sweet potato a good meal replacement?

Sweet potatoes replace dinner, but it doesn't mean you can replace the whole dinner with sweet potatoes. To lose weight, the total calories should be well controlled. Although the calorie intake at night may be a little low, it is also important to pay attention to the diet in the morning and at noon, otherwise you will eat more in the morning and at noon, otherwise you will still be fat.

Sweet potatoes are the best substitute for some staple foods. Simply eating sweet potatoes alone is not nutritionally balanced and can easily lead to malnutrition over a long period of time. Whole grains such as sweet potatoes and corn can replace staple foods such as steamed bread and rice.
