Under the native forest of orchids, the sex is yin and afraid of the sun; avoid hot, dry, and require a well-ventilated environment. According to this growth habit, the maintenance of orchid summer and autumn must pay attention to four points: Shady and ventilated orchids are shaded from early summer to the end of September. The shade should not be less than 70%. When shading, a large amount of shade nets are used, and the amount is small placed on the north balcony and under the eaves. Plants should be placed in this period, and the pots and pots should be no less than 10 cm. It is best to use bricks under the basin to increase the ventilation and ventilate it. In addition, it is necessary to prevent the pollution of harmful substances such as sulfur dioxide, hydrogen fluoride and dust, and promote its robust growth. The suitable growth temperature for cooling and humidifying orchids is 20 °C to 28 °C, and the growth is rapid above 25 °C. When it exceeds 32 °C, it is forced to enter the dormant period, and the growth is in a stagnant state. When the temperature reaches 30 °C, it is necessary to take measures to cool down and humidify. In the open air, you can lay river sand or plastic film on the ground, raise it on the balcony, and put a sponge under the basin, which is always moist. Spray the plant several times a day and sprinkle water on the ground. Indoor maintenance can be done by air conditioning or electric fans. Adjust the temperature to below 30 °C as much as possible, and stabilize the air humidity above 70%. Watering and fertilization At present, most of the orchids are cultivated in the soil, and most of them are potted plants. The soil moisture of the basin should adhere to the principle of “running but not damp, dry but not dryâ€. The watering should be carried out when the topsoil is slightly white. Do not over water, causing rotten roots. From midsummer to early autumn, it is generally poured in the early morning water, and the water is treated as appropriate according to the dry and wet conditions of the basin. If the potting soil is found to be dry after noon, it is necessary to replenish water at any time. After the Mid-Autumn Festival, although the climate is getting colder, the air is dry. According to the requirements of “autumn not dryâ€, it is advisable to keep the soil moist. Fertilize the orchids in a small amount, thin, diligent, and timely. This is especially true in summer and autumn. May-September should be fertilized according to different orchid species and different growth stages. Fertilization is suspended for orchids that are in dormant period or when the temperature is above 30 °C. The application of liquid fertilizer is generally 15-20 days, the ratio of fertilizer to water is 1:10, and the room is solid fertilizer. Scale production of multi-purpose fertilizer, the concentration is about 0.1%. Foliar spray fertilizer concentration is prepared according to product specifications. Disease prevention and pest control orchids are plants with many pests and diseases, especially in the high temperature and high humidity season. Anthracnose is the peak period from June to September, and carbendazim and thiophanate have better control effects. The sputum is treated with chloramphenicol injection 500-1000 times liquid, once a day, twice in combination, to control the disease. Scale insects are the enemy of orchids. Adults are removed by hand. During the hatching period of May-June larvae, they are sprayed with drugs. The aphids and whitefly are sprayed with 10% wettable powder 500 times, and sprayed twice continuously. Disclaimer: Some articles on this website are transferred from the Internet.

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%.

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.
