How to maintain the continuity of grow plug orders? And how to choose plants to enter the nursery to improve seedling efficiency and the process of seedling reproduction?
Artemisia annua has a short grow period, and some of its drawbacks are different from seedling cultivation methods and traditional methods. When using traditional sowing methods, both sowing and field planting are used. When raising seedlings, the temperature is high and direct seeding is required.
During the sowing and seedling cultivation period, the temperature should be maintained at 18-20 ° C. After sowing, the small seedlings should be ventilated and nutrient solution should be sprayed on a basin of more than ten square meters. It is recommended to spray dry vegetables thoroughly each time. As the moisture content of the seedlings increases after they grow, appropriate water spraying or fertilization equipment should be added to achieve larger grow requirements. The effect of flushing fertilizer is better than that of conventional fertilizer, but it should be watered and added with nutrient solution to ensure the normal grow of seedlings. Spray once every 10 days, continuously 2-3 times. During high temperatures in summer, it is necessary to extend the watering cycle appropriately to form moist soil. In the afternoon, all watering should be done after sunrise.
When choosing cloudy days, it is necessary to avoid light. It is not advisable to spray water on rainy and snowy days. Due to the unsuitable layout of the greenhouse for vegetable grow, and the room temperature at night is generally not lower than 26 ° C, vegetable plants can only grow. After the chili peppers slow down, they should be immediately let go of the wind. There are also six points to ventilate when the temperature drops to 15 ° C.
Vegetables, fruits, flowers, etc. in vegetable greenhouses should be listed in advance. According to market research, high-quality varieties, and vegetables listed in different seasons, and according to market research and the requirements for off-season listing, combined with the actual production situation in local townships, stubble arrangements should be selected.
Due to the heavy rainfall and high air humidity in the autumn and winter seasons, watermelons are prone to overgrowth. Once there is insufficient fertilizer and water, they are easily affected by overgrowth. Therefore, growers should take effective measures to increase fertilizer and water levels in autumn and winter, and timely carry out field management.
In order to effectively improve the quality of vegetables, it is necessary to increase the application of Manure and improve the nutritional status of protected vegetables. The market value can be said to increase capital, but under natural conditions, the cost of fertilization is relatively high; So, when applying sufficient fertilizer or causing losses to vegetables due to poor fertilization. When it comes to "soilless cultivation", continuous cropping is a common fear, and implementing "continuous cropping" fertilization is a good method for addition and killing three birds with one stone. So let's
