Oil wheat vegetable cultivation time and planting method
The taste of oily wheat vegetables is particularly like lettuce leaves. Many people will ask if they are the same kind of vegetables. In fact, oily wheat is a kind of lettuce, which is a kind of lettuce with pointed shoots and young leaves. Let's take a look at the key points of planting techniques for oily wheat.
Planting time
The growth adaptability of the oily wheat is very high, basically it can be planted as long as the temperature is enough. The normal cultivation time of the oily wheat is between mid-April and mid-May or August and September. If planted in winter, it is generally a greenhouse cultivation mode.
2. Soil preparation and fertilization
Deep ploughing should be carried out during the preparation of the ground, and the base fertilizer should be applied adequately. The base fertilizer is usually based on farmyard manure. At the same time, we can combine the urea, potassium sulphate, diammonium phosphate and compound fertilizer to stir evenly and then plow the plough.
3. Nursery
(1) Chang nursery transplanting
The germination temperature is 15 to 20 ° C, higher than 25 ° C or lower than 8 ° C does not germinate, so it is necessary to germination during high temperature in summer. Spread the seeds on the water-soaked soil surface, cover the soil about 0.5 to 1 cm, keep the soil moist, and germinate for about 1 week. (Promoting method: soak the seeds in water for 4.5 to 5.5 hours, dry them slightly, wrap them in a damp cloth, place them in a cool place to germination, and plant about 3/4 seeds when they are white.)
(2) The soil in the seedling stage should be kept moist, and it should be shaded during the summer exposure. When the true leaves are 3 to 4 pieces, they are planted in the potting soil where the base fertilizer is applied. The plant spacing is about 10-15 cm, and the water is poured through the water. It can be managed normally after about 1 week.
4. Timely planting
The colonization of the oily wheat seeds can be carried out in about five or six days after germination. The spacing between the plants is generally 20 cm and the spacing between the rows is 15 cm.
5. Field management
The oily wheat has less pests and diseases, rapid growth, and large amount of fertilizer. Generally, it is sprayed once every 7 to 10 days with decomposed organic fertilizer mainly based on nitrogen fertilizer to promote leaf growth. It is advisable to stop fertilizing 1 week before harvesting; It is cool, slightly cold-resistant and not heat-resistant, and the leaf growth temperature is 11-18 °C. If the temperature is too high, it will affect the growth or flowering in advance; the oil wheat lettuce is moist, and it needs to be given sufficient water during the vigorous growth period, usually watering once a day. Water if necessary, early or late, so as not to affect the quality of the leaves.
6. Harvest
Harvesting takes about one month after planting, or from about 15 leaves, usually in the morning, and the green leaves that are fully grown, thick and crisp are hand-cropped. After harvesting, after the wound is dried, the decomposed organic fertilizer can be applied once to promote the germination of the new leaves, and it can be harvested again after a period of time.
The above is the cultivation technology of oil wheat vegetables. I hope that the farmers who want to grow oil and wheat vegetables will be helpful. Farmers who have more comprehensive planting experience are welcome to share their experiences.

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.
