The latest tribute vegetables cultivation technology tutorial
Gongcai is an annual herb. Gongcai has a bright appearance, good taste and high edible value. It is a kind of high-grade dehydrated vegetable in our country, because it was paid tribute to Qianlong during the Qing Dynasty, and was wantonly praised by Qianlong, and then paid tribute year after year, so it is called tribute vegetable. So how to grow tribute vegetables? The following editor brings you the planting technology of tribute vegetables, let's have a look!
1. Soaking seeds to accelerate germination
The planting time of tribute vegetables is generally around Ching Ming Festival every year, and it is best to sow around 8 days after the Beginning of Autumn. However, because the seeds of Gongcai are difficult to germinate in a high temperature environment, it is necessary to treat the seeds at a low temperature before sowing. Soak the Gongcai seeds in cold water for about 3 hours, if you need to remove the seeds and drench them in cold water every day. If the temperature is too low, you need to do a good job of shading. If it lasts for about three days, the seeds will almost sprout. Soaking seeds to promote sprouting is the most important step in the cultivation of tribute vegetables, which can not be ignored.
2. Soil preparation and sowing
The growth ability of Gongcai is relatively strong, and the yield is also relatively high, but the premise of high yield is based on the soil. Although the adaptability is strong, the yield will certainly be affected after survival, so Gongcai should be planted on sandy soil with alkaline, sufficient fertility and strong ability to conserve water and fertilizer. After selecting a good site, do a good job of soil preparation, carefully check whether there are any residual herbicides or pesticides, and deal with them in time if found, so as to avoid drug damage, ploughing and soil preparation, improve soil fertility, enhance permeability, and reduce the incidence of disease. After soil preparation, the sowing density was planned reasonably, and the planting holes were dug to sow seeds after the Beginning of Autumn, so as to provide a good environment for seed growth.
3. Field management
Gongcai sowing because the temperature has not completely dropped at that time, the rate of water evaporation is faster, and Gongcai seeds are relatively small, the top soil capacity is poor, so we should pour enough water after sowing to promote seed germination and emergence. Water at least twice a day, but not too much water, to ensure that the soil can be moist, after watering covered with straw and other mulch to prevent water loss. When the seeds emerge, the straw should be removed according to the seedling situation and time, and the weeding work should be carried out frequently to prevent soil consolidation and weeds from affecting the growth of seedlings. Do a good job of topdressing to ensure adequate nutrition for the growth of Gongcai seedlings and avoid malnutrition
4. Timely harvest
The quality and output of tribute vegetables are closely related to the harvest time, and the harvest should be timely, not too early or too late. If harvested too early, the tribute vegetables are not mature enough, resulting in a serious decline in output. Purchasing too late is easy to make Gongcai hollow, the crude fiber in the plant increases, the quality decreases, and is not conducive to storage. The harvest time is determined according to the plant condition and planting area, for example, the outer leaves of the on-duty plants can be harvested after leveling with the heart leaves.
The above is a brief introduction of Gongcai planting technology, Gongcai has a large demand for fertilizer and water, especially in the growing period, the nutritional demand will be further increased. Therefore, in the hair stage of the hand should pay attention to fertilizer and water management, timely watering good hair water, to promote the growth of tribute vegetables. That's all for today's introduction. This article is for reference only. I hope it can help you all.
