Greenhouse potato-watermelon-summer bean-cucumber cultivation mode of four seasons, 667 square meters of potato 1000kg ~ 1500kg, watermelon 2000kg, summer kidney bean 500kg ~ 800kg, cucumber 1500kg, significant economic benefits, its main The technical points are as follows:
I. Import and export arrangements
The potatoes are sown in the greenhouse in late November and harvested in late March of the following year. Watermelon nursery in late February, planted in greenhouses in early April, harvested in late June and can remove greenhouse film at the same time; summer kidney beans are broadcast live at the end of June, harvested in the middle and late August; cucumbers in late autumn are in early August Nutritional nursery, planted in early September, covered in mid-October, can be harvested in mid-to-late October, and harvested at the end of November.
Second, technical points
1, potato
Choose high-yield, high-quality, disease-resistant varieties "double harvest", do not cut into pieces. Combined with winter tumbling, 667 square meters of fermented organic fertilizer 3000 kg ~ 4000 kg, compound fertilizer 40 kg. The plant spacing is 50 cm × 20 cm, and 667 square meters are planted with about 6000 plants. After sowing, the fine soil is covered with 7 cm to 8 cm. The flat surface is flattened and the mulch is covered.
When the seedlings are emerged, the seedlings must be broken. Generally, a small amount of nitrogen fertilizer is applied after emergence, and the seedlings are fertilized before being sealed. After the closure, the fertilizer is not applied, and the soil irrigation is determined according to the public opinion. To promote the combination of control, the flower buds can be removed, and the paclobutrazol is sprayed once in the bud stage and the flowering stage to control the plant length. The medicament prevents late blight. After maturity, the vines are buried in the soil and ploughed.
2, watermelon
Choose varieties such as early maturity, disease resistance, and good commercial quality. Soak seeds with warm water for 3 hours to 4 hours before sowing, then germination for 24 hours at 37 ° C, and sow seeds in the nutrient bowl after 50% of the seeds are exposed. Fine land preparation before planting, uniform fertilization, 6 m wide shed made of two rafts, ditch depth 20 cm, width 30 cm, two sides along the ditch planted, two rows planted along the shed side to extend outside the shed, 6 m shed Planted 4 rows, plant spacing 50 cm × 200 cm. 667 square meters planted 600 to 700 strains.
When the seedlings turn to green after planting, the seedlings are topdressed with 0î€5% urea solution before the vines are poured, and the double vines are pruned. After the 12th section of the main vine, the melon is usually kept stable. When the top grows slowly, stop the pruning and snoring. In the melon expansion period, chase the second fertilizer, and the compound fertilizer will apply 50 grams per plant (point). Fertilization of potassium dihydrogen phosphate leaves. Water supply is guaranteed throughout the growing period. In early May, the skirt side mask was uncovered, and the edge of the greenhouse was stretched out along the watermelon vine. The whole growth period of watermelon is used to prevent blight, anthracnose, epidemic diseases, pest control and yellow squash and aphids.
3, summer kidney beans
Choose the early maturity, disease resistance, high temperature resistance of the special early 30, the 28-2 variety. Apply enough base fertilizer, apply 3,000 kg to 4000 kg of organic fertilizer per 667 square meters, 30 kg to 40 kg of superphosphate, 20 kg of potassium chloride, 20 cm deep, 耙 flat for 畦, 畦 high 20 cm, width 80 cm, The groove is 30 cm wide.
Dry seed live, plant 5 leaves to 6 leaves in time to frame, while applying a small amount of dilute water for seedling fertilizer, harvest for the first time, combined with irrigation and urea, compound fertilizer, appropriate top dressing, anti-premature aging, diligently ploughing, Anti weed. Pest control pests, rust, and insect pests are harmed by drugs to control mites and bean mites.
4, Qiuyan cucumber
The varieties such as Jinyan No. 4 and Jinyou No. 1, which are heat-resistant, disease-resistant, dense, high-quality and high-yield, are used to breed seedlings. Before sowing, the seeds are exposed to sunlight for 2 days, first soaked in water for 4 hours to 6 hours, soaked in warm water at 55 ° C for 15 minutes, continuously stirred, and then drained and drained. After harvesting, the sorghum is deeply turned 20 cm to 25 cm in length, and is made into a scorpion with a height of 20 cm and a width of 80 cm. The width of the gully is 50 cm. Combined with the preparation of the ground, every 667 square meters of rotted organic fertilizer is 2,000 kg to 3,000 kg, and the compound fertilizer is 40 kg. .
The planting density is 25 cm × 40 cm, and about 3,500 plants are planted at 667 square meters. When the plants start to vine, they will stand up in time. Seedlings 2 to 4 leaf stage with a concentration of 150 mg ~ 200 mg / kg of ethephon spray, to the degree of leaf surface moistening, increase the number of female flowers. Topdressing masters the principles of light application, diligence, and sub-application. Shiti Miao fertilizer 1 time ~ 2 times, with a weight of 500 kg per 667 square meters of dilute water, before the scaffolding, apply a small amount of manure water to 667 square meters of 1000 kg, and then harvest 1 to 2 times each time, then each 667 square meters of 10 kg of urea or 15 kg of compound fertilizer for supplement.
Cucumber requires a large amount of water during the fruiting period. It should be watered up, water is even, and a small amount of times, do not engage in flood irrigation. The disease of Qiuyan cucumber is mainly downy mildew, blight, blight, 77% can kill 500 times liquid or anti-virus 矾 600 times liquid to control downy mildew; 70% methyl thiophanate 1000 times liquid or 25% Metalaxyl 600 times liquid against blight and disease. 80% dichlorvos 1000 times liquid to prevent yellow squash. It is necessary to take early and early harvest, pick the roots early, increase the number of harvests, and increase the population output.
Probiotics are a group of active microorganisms that are beneficial to the host by colonizing the body and changing the composition of the host flora in a certain area. It is a single microorganism or a mixture of microorganisms with well-defined composition that can produce beneficial effects on health by regulating the immune function of the host mucosa and system or by regulating the balance of flora in the intestine and promoting nutrient absorption to maintain a healthy intestine.
The probiotics that scientists have discovered so far can be broadly divided into three major categories which include.
â‘ Lactobacillus class such as Lactobacillus acidophilus, Lactobacillus casei, Lactobacillus janus, Lactobacillus lamanis, etc.
â‘¡Bifidobacteria category such as Bifidobacterium longum, Bifidobacterium shortum, Bifidobacterium ovale, Bifidobacterium thermophilum, etc.
â‘¢ Gram-positive cocci such as Streptococcus faecalis, Lactococcus lactis, Streptococcus intermedius, etc.
