Great heat is the hottest season of the year, with high temperatures of 40 degrees Celsius often occurring. Rainstorms, hailstorms, and high winds are also frequent occurrences. It is the fastest growing period for hi-heat crops. In this hot and unbearable season, the farm field is busy and the work of the vegetable farmers in preventing heatstroke cannot be ignored. We must do a good job in the sowing of autumn crops, nursery and field management, and we must do a good job in preventing floods and preventing disasters.
Autumn crops with open field crops
Carrots and cabbages planted in the open field are planted in late July. The Dahongpao radish is sown in the appropriate period from late July to early August. It is necessary to apply organic fertilizer as base fertilizer and improve the quality of the soil preparation to make it about 15 cm above the ground. Sorghum seeding, watering and cooling after sowing. In the open field, some heat-resistant leafy vegetables such as leeks, mushrooms, spinach, coriander, and spinach can be sowed in batches, which can be listed in the off-season in August and September to make up for the lack of market supply.
Autumn crops nursery and seedling management
The tomatoes, peppers, bell peppers, eggplants and other crops grown in the greenhouse in autumn and winter are being planted for a suitable period. To select nursery sites, we must also do a good job of seed disinfection and treatment, and focus on the prevention and control of tomato yellow leaf curl virus. The crops such as cauliflower, cabbage, lettuce, celery and lettuce cultivated in autumn eucalyptus are in a critical period of nursery management. At this time, they are high in temperature, rainy, susceptible to seedlings and pests, and are subject to temperature regulation, shading, rain protection, and prevention. Diseases and pests work to breed age-appropriate seedlings in adverse climate conditions.
Colonization of tomatoes and cucumbers in autumn greenhouses
In the latter part of July, the planting period will be appropriate. The clean pastoral work after the harvesting of the previous crop will be done. The stubble, rotten leaves and weeds in the shed will be removed in a timely manner and transported to designated locations for high-temperature disinfection and other harmless treatment. . Apply adequately cooked, finely-divided organic fertilizer as a base fertilizer, plant it on a sunny day, and pour enough water for planting in time.
Summer Vegetable Management and Harvesting
In summer and summer vegetables such as loofah, bitter gourd, wax gourd, pepper, eggplant and tomato planted in greenhouses, it is necessary to strengthen field management such as pruning, assisting pollination, promoting fruit setting and other field management, and doing a good job of shading and controlling diseases and insect pests, especially focusing on virus diseases. , whitefly, red spider and other pests and diseases. According to the weather conditions, soil conditions and plant growth, timely top-dressing water can be used to promote the growth of plants that are not long, premature, and have high rates of multi-bread crops. To harvest ripe fruit in time, it is best to harvest it in the early morning on a sunny day so that it is of good quality.
Chinese cabbage soil preparation and fertilization
Remove the stubborn leaves, rotten leaves, and weeds as soon as possible after the front rake, and transport them to designated locations for harmless treatment such as high-temperature composting. Then, apply mutified, finely ground, high-quality organic fertilizer 4-5, or commodity organic fertilizer. Tons, fine ground preparation after spreading and waiting for sowing.
Onion Management
The soil should be watered in time when the soil is dry, and the land to be planted early should be sub-cultivated, and the weeds in the field and the ground should be removed to prevent and control the pests such as the thrips.
Do a good job of field flood control and greenhouse rain
The field drainage ditch shall be dredged in time to prevent blockage, so that after the rainfall, there will be no accumulation of water in the field and the land will not collapse. We inspect and repair weak parts such as greenhouse walls and roofs, and check the insulation of thermal insulation materials and grasshopper insulation materials to prevent damage caused by leakage.
