The next day, Xiaohua suggested to Uncle Xu at home. Since we have a win-win relationship with farmers, and all the Chinese cabbage in a greenhouse has been eradicated, can we use this greenhouse to use soilless cultivation technology to provide high-quality fresh vegetables for our feast of love.

If this soilless cultivation technology is successful, it can also give farmers a demonstration base. Drive the common development and progress of surrounding farmers. Uncle Xu said: "Xiaohua, your idea is very good, we will go to the agricultural market now to purchase soilless cultivation objects." ”

A total of 20 sets of planting racks were purchased, as well as planting boxes, perlite, grass ash, humus, drip irrigation equipment, and atomization equipment. We hired a truck to bring all these items with us.

As the car drove on the top of the mountain, you could vaguely see the greenhouses under the mountain. Entering the location of the greenhouse, the farmer uncle had already learned the news and organized personnel to wait outside the greenhouse.

First of all, the 20 groups of planting frames are built, the columns on both sides are erected first, and then the top struts are installed, and the piston is hooked inside, and then the bottom struts are installed, and after the surrounding is fixed firmly, then the first, second, third and fourth layers of partitions are inserted. Place the planting tray on the planting rack, and then put perlite, grass ash and humus in the planting box. Xiao Hua said: "I'll plant a box too." She dug a small hole, buried two or three seeds, covered them and pressed them lightly with her hands. Then drip irrigate the nutrient solution.

The farmer said: "Xu Guochu, can you survive like this?" Xu Guochu said: "No problem, soilless cultivation technology is to artificially create a root environment and replace the soil environment. The farmer said, "I haven't seen that man grow vegetables like this." ”

Xu Guochu said: "At present, there are many places in China that are adopting modern soilless cultivation technology, and it has achieved great success. The farmer said, "Will people approve of this vegetable?" Sell it? Xu Guochu said: "Now many people use this method to grow vegetables on the balcony of their homes!" ”

The varieties planted are, water spinach, cucumber, lettuce. Water spinach is a spiral flower, with white trumpet flowers, hollow stems, water spinach has heat clearing and detoxification, crude cellulose, and high vitamin content. Water spinach has the effect of sterilization, and eating it in summer has the effect of preventing heatstroke and cooling down. Eating water spinach often can also detoxify and detoxify.

Cucumber belongs to the Cucurbitaceae family, the stem is slender, the leaves are triangular, the flowers are yellow and white, and the cucumber grows in the vegetables of the western Himalayas. Cucumbers are cool and sweet, contain a lot of water, clear heat and relieve heat, relieve sore throat, and promote urination.

Lettuce originated in the Mediterranean, introduced to China in the Tang Dynasty, lettuce with hypertrophied stems as the edible part, there is a layer of fiber layer outside, which plays a protective role in the inner stem. The leaves are pointed. Lettuce has a fresh and slightly bitter taste, which stimulates the secretion of digestive enzymes. Strengthens the body with a wide range of vitamins and minerals. and absorbable iron.

The people in the village heard that the soilless cultivation planting rack was assembled, and everyone came to visit, and the planting rack was neatly arranged in the greenhouse, with good light, fresh air, no peculiar smell, and cheap management.

The villagers came in and touched the planting rack and said: "What kind of materials are these made of, whether they are connected or not, how many boxes of vegetables can be planted in one planting rack?" The small painting said: "This is made of alloy material, which is very strong. If you increase the number of layers, you can also have a variety of vegetables. ”

Soilless cultivation technology is a new planting method developed in recent years, crops are planted in the soil, with the cultivation method of nutrient solution, soilless cultivation of vegetables, high yield, rich nutrition, good taste.

Xiaohua said to the farmer: "In the future, we can also expand the greenhouse of soilless cultivation to solve the supply problem of fresh vegetables." The farmer said: "If the market sales are good, we will participate in the planting rack." ”
