1. The first kale cabbage 1 seedlings. The disease-resistant, early-maturing and high-yielding varieties 8398, Zhonggan No. 11 and Primula were used for the cultivation of Yangshuo from mid-November to early December. According to a 10 square meter seedbed, 20 kg of decomposed cyclization, 5 kg of chicken manure, and 3 kg of calcium phosphate were used to make bed soil. After sowing, keep the temperature during the day at 20-25°C and the night temperature at 5-10°C. After the seedlings are discharged, cool the air and cool it down. Grasp the daytime temperature 10-15°C and nighttime temperature 2-7°C. Do not water without drought, avoid long and big seedlings overwintering. In mid-December, when the seedlings grow to 2 leaves and 1 heart, the seedlings move. After sub-seedling, the temperature of the alfalfa is raised to 15-20°C, and the temperature is reduced to 10-15°C after the seedlings are released.
2 transplanting. Transplanting is carried out from mid-January to early February. Before transplanting, it will be used for fine soil preparation and forging. The Mushi organic fertilizer will be 3000-4000 kg in the bottom rot, and 60 kg of compound fertilizer will be scattered. Then the ridge will be ridged, the width will be 2.5 meters, and a small arch shed with a width of 4 meters will be used. cover. The sorghum flour is planted in the east-west direction, and each row is planted with 6 rows, with a spacing of 35 cm and 3800-4000 plants per mu.
3 management. The cabbage was watered immediately after colonization. During the seedling period, when the temperature in the shed is 18 to 22°C, ventilation begins to adjust the seedlings, and the seedlings are reduced to 1-2 times of cultivating during the lotus period. In combination with watering during the filling period, the water is top-dressed twice. Each time, the amount of nanopaste 20 kg and compound fertilizer 25 kg are dissolved in water per mu. Depending on soil moisture 10-15 days pouring 1 water. From mid-March to early April, when the leaf ball grows to 1-1.5 kg, it can be marketed.
2. The second green pepper 1 seedlings. High-yield, disease-resistant varieties Zhongjiao 7, Jingtian 2, etc. were selected, and they were planted in late October-November. Seedlings were grown for about 120 days.
2 colonization. From the end of April to May 1st, cabbage was harvested and transplanted with green peppers. Each row had 4 to 5 rows and were planted on rows of cabbages, with a spacing of 40 cm and 3,000 shoots per mu. With planting per acre sprinkler compound fertilizer 40-50 kg.
3 management. After the planting began, the peppers began to swell, and the first time the morning fertilizer was applied for watering on sunny days, the nanopaste and compound fertilizer that were dissolved in advance with water were applied along with water, and 20 kg of nanopaste was applied per acre, and the compound fertilizer was 25 kg. Every pick one pepper top dressing 1, watering about 7-10 days. Green pepper planting, the temperature within the shed shall not exceed 30 °C, generally 2-4 days do not release the wind, then depending on the weather conditions release, from small to large, vents can not meet the wind direction, so as not to flash seedlings. The daytime temperature is controlled between 25-30°C and it is controlled at 10-15°C during the night. When the outside temperature is suitable for the growth and development of green peppers, the protection facilities can be dismantled so as to avoid excessive temperature in the shed, resulting in falling flowers and falling fruit. When the rate of fruit set falls in mid-June, it is necessary to strengthen fertilizer and water management, spray foliar fertilizers and bactericidal agents, prevent disease and protect leaves, drain water after flooding, and promote root growth.
The main disease prevention and control: Virus disease was found, and it was controlled with the A500 liquid of the virus. Anthrax was treated with 600-800 times of tetromycin or 800-1000 times of thiophanate-methyl.
3. The third crop of autumn cucumber 1 selects the appropriate variety. Choose heat-resistant, disease-resistant varieties, such as Tang Qiu 1, Cuiguan and so on.
2 Shizu base fertilizer. After harvesting on the last crop (from late July to early August), 7500 kg of circulated fertilizer is applied per mu, 1,000 kg of chicken manure or large manure, 40 kg of superphosphate, and 100 kg of vegetation ash. Then exterminate the deep turn, rub even leveling.
3 sowing. Using dry seed live, groove distance 50 cm, ditch depth 3-4 cm. When the soil moisture is poor, it can be watered and moistened. Seeds are planted at a spacing of 25 cm and 3 seeds per pier.
4 management. Cucumbers before the melon, due to more rain, the soil is easy to water stains, affecting the root development, should be fine and timely scratching, sticky wetland can be ditch, in order to facilitate the exclusion of field water immediately after the rain. In addition, spray 0.2% of potassium dihydrogen phosphate and 0.1% of zinc sulfate mixture every 7-8 days for foliar cooling. To combine top-dressing Sacofu compound fertilizer with watering, generally apply 10-20 kg per acre. Weeding and pruning should be done in time to facilitate ventilation and light transmission in the field.
Timely prevention of pests and diseases. Summer and autumn are hot and rainy, cucumber downy mildew, powdery mildew, bacterial angular spot, blight, epidemic and anthrax, and locusts and red spiders are highly prone to occur. Comprehensive control should be carried out using a combination of pesticides and cultivation measures.
