Change the soil. According to the different soil textures, the soil is improved by the method of changing the soil. For the soil that is too heavy, it should be properly mixed with sand and river mud for improvement; for sandy soil with poor water retention and poor fertilizer retention, it should be mixed with appropriate amount of clay for improvement.
Improve soil organic matter content. A large amount of fertilized organic fertilizer is applied and supplemented with chemical fertilizer. Apply 5,000 to 10,000 kilograms of organic fertilizer per 667 square meters, and evenly spread it after planting to mix it with the soil. Wherever possible, green manure can be planted to increase soil fertility.
Expand the matured soil layer. The agricultural soil layer is shallow, usually about 15 cm, and there is a dense plow bottom. After being converted into a vegetable garden, the method of gradual deep tillage can be adopted to deepen the tillage layer. After deep tillage, the soil tillage layer is 20~25 cm, and the mature soil layer is 30~50 cm, forming a deep loose soil layer and expanding the absorption surface of the root system. Supply nutrients and moisture.
Appropriate application of chemical fertilizers. Vegetables absorb much more nutrients than field crops. In addition to nitrogen, phosphorus and potassium, the absorption of calcium, magnesium and other elements is also more. After Datian is changed to vegetable garden, the application amount of nitrogen, phosphorus and potassium fertilizer should be increased, and it should be rationally applied according to the different types of vegetables to avoid partial application of nitrogen fertilizer. In soils with insufficient supply of calcium and magnesium nutrients, it is necessary to apply calcium fertilizer, magnesium fertilizer or fertilizers containing calcium and magnesium, such as calcium magnesium phosphate fertilizer, calcium superphosphate, potassium magnesium sulfate, boron magnesium fertilizer and the like.
Pay attention to planting techniques. The newly-reformed vegetable garden soil is initially planted with vegetables that require less fertilizer and water. Such as peas, onions, cabbage and so on. After a period of planting, the degree of soil ripening is improved, and after the improvement of water, fertilizer, gas and heat conditions, vegetables such as tomatoes and cucumbers which require higher soil fertility are planted.

Sweet corn. The light green outer leaves of sweet corn are yellow grains, but also purple and yellow. The grains are small and round, the skin is thin and soft, tender, sweet and delicious.Contains carotene, zeaxanthin, with the effect of eye protection.
Sweet corn is most often boiled into soups. It is a favorite soup for children and adults, whether it is made into a clear corn soup with ribs or pureed with cream.
Corn is also a good choice for consumption during weight loss because of its high available energy. The metabolic energy of corn is 14.06 MJ/kg, with the highest being 15.06 MJ/kg, the highest of the cereal feeds. This is mainly due to the fact that there is very little crude fibre in corn, only 2%, while the nitrogen-free leachate is up to 72% and the digestibility is up to 90%; on the one hand, corn has a high crude fat content, between 3.5% and 4.5%.
So how do you cook a sweet corn?
1. Leave the leaves
If you strip the leaves off, the corn will lose nutrients and flavor when it cooks, so it's best to leave two thin leaves to make it easier to cook and have a nice aroma.
2. Soak
Soak the corn in cold water for 20 to 30 minutes before boiling, then boil it on high heat to give it a bit more chew.
3. Add salt
When the water is boiling, add a little salt to amplify the sweetness of the corn.
