Steel greenhouse vegetable efficient three-dimensional planting

The village of Ertang, Yicheng Town, Yishui County, Shandong Province is located in the outskirts of the city. The per capita land area is less than 667 square meters. For many years, farmers have been earning a living by growing vegetables, but economic efficiency has not always improved. Obviously, it is difficult to increase the economic efficiency of farmers by relying solely on traditional planting methods. In recent years, with the increase of government investment in agriculture, Ertang Village has built more than 53.33 hectares of steel frame sheds for the development of efficient agriculture. The technical staff of the Agricultural Technology Station in Lucheng Town used the advantages of the skeleton of the steel frame and the shade of the lentils to guide the peasants to develop three-dimensional planting techniques of eggplant, lentils, summer cabbage, and autumn beans based on local production conditions. In 2007, Zhang Yunbiao, a large vegetable producer, produced 4,000 kg of eggplant, 1,000 kg of lentils, 2,000 kg of summer cabbage, and 1,000 kg of autumn beans per 667 square meters, with an efficiency of 15,000 yuan/667 square meters. The remarkable increase in economic efficiency has enabled this technology to be fully promoted locally. The main cultivation techniques are now described as follows:

1. Planting mode Eggplant seedlings were planted in early December and harvested in early March of the following year. Harvesting was completed at the end of June and the beginning of July. Lentils were planted in the early and late stages. Early lentils were planted in early January and planted in late February. Late lentils were planted in early March and planted in early April. Batch harvesting began in early May and harvesting ended at the end of July. Summer cabbage is sown in early July and harvested in late August and early September. The autumn beans were sown in early August and harvested in late September. In mid-October, they were cleared.

2. Cultivation points Eggplant uses precocious and high-product varieties such as Jiha 1. Eggplant seedlings were planted with 7 to 8 true leaves. The plant spacing was 70 cm and 35 cm, and 2,500 plants were planted per 667 m2. In early spring, the greenhouse was cultivated in a four-layer cover (house + grasshopper + shed + mulch). 20 to 25 days before planting, apply 40 to 50 kg of farmyard fertilizer per 667 square meters, 1000 to 1500 kg of chicken manure, and 40 to 50 kg of 45% ternary compound fertilizer. Mix well with the soil and snail the membrane. Warming. Post-planting management: During the day, the shelf temperature is maintained at 25 to 30°C, and ventilation and cooling should be performed in excess of 35°C. The temperature at night can't be lower than 15°C. In the early stage of growth, it is generally not necessary to apply water to fertilize. The main control is to promote the growth of the phytospermia of the phylum. The leaves are preserved before and after flowering, and the pods are preserved before and after flowering. The initial flowering period is 4010-6 to 5010-6. Add 0.1% quick keratin mixed flower stalk to increase fruit setting rate. On the basis of controlling temperature and humidity during eggplant harvesting, it is important to prevent botrytis, sclerotia, and spotted fly.

Lentils are selected from the best-selling red lentils on the market. They are used to grow seedlings in greenhouses in early January and early March respectively, with 2 to 3 capsules per seedling. The first lentils were planted in the middle of the greenhouse between the rows of eggplants, and were planted in 2 rows with a spacing of 1 metre. After the second lentil was removed from the shed, the lentils were planted on the lower foot of the steel tube and only 1 hole was planted. Row. A total of 4 rows of lentils were planted in the whole greenhouse, and 450 holes were planted per 667 square meters. Post-planting management: the initial flowering period of lentils is to use 5010-6 anti-dropping spray, 5 to 7 days for 1 spray, and 3 to 4 sprays to increase the rate of scarring; when the lentils are harvested in less inflorescences, 15 can be used. % 8 grams of paclobutrazol spray 10 kg of water on the foliage, increasing the weight of the pod. In mid-June, lentils entered the blooming stage. Each 667 m2 of acupoints was applied with 45% of three-component compound fertilizer and 15 kg of urea plus 10 kg of urea. Spring lentil disease is generally less in greenhouses. There are mainly insect pests such as aphids, spider mites, and soybean meal. Imidacloprid and broomstick nets can be used for prevention and control. After the harvest of early summer cabbage, the empty plot is ploughed and planted. The loquat is 30 centimeters high, 1.0 to 1.2 meters wide, 40 to 50 centimeters deep, 25 to 30 kilograms of diammonium phosphate per 667 square meters, and 80 g. -100 kg, soil treatment with 5 kg carbendazim 1.5 kg. Xia cabbage uses heat-resistant, short growing period, strong resistance varieties, such as Xia Yang 50, Xia Shu, on-demand in early July, sowing each hole 3 to 5 tablets of Health, row spacing 40 to 50 cm 30 cm, every 667 Square meters with 100 ~ 150 grams. 2 to 5 leaves during the seedlings, 7 to 8 leaf stage Dingmiao, planting about 4,000 square meters per 667 square meters. In addition, we must promptly prevent and cure cabbage worm, Spodoptera litura and cabbage soft rot. During the lotus period, good ball fertilizer should be applied. Autumn beans are selected for early maturing and high-yield cultivars, such as regular kidney beans No. 3. In early August, live in the summer cabbage between the rows, 3 to 4 per hole, spacing between rows of 60 cm 20 cm, the amount of 3.5-4.0 kg per 667 square meters. After the whole seedling and time seedlings, Dingmiao, 2 seedlings per 667 square meters. When the seedling height is about 25 cm, bamboo vines are used to introduce vines, and vines are put on the scaffolds. Before and after the shelves are properly chased with fertilizers, 2,000 square meters of high-quality human and animal manure is applied every 667 square meters. At the end of August and early September, 15 kg of urea and 15 kg of urea were applied to 667 square meters of compound fertilizer. Paying attention to crop rotation to reduce soil-borne diseases, we must focus on the control of Spodoptera litura, soybean meal and rust.
