Postponed vegetable production management technology
The high temperature in September has passed and the weather has turned cold. Vegetable production has entered a busy season.
First, sowing, nursery
1, greenhouse vegetables. In September and October, greenhouse eggplant, tomato, and pepper are planted and cultivated in winter. The temperature is high, rainfall is high, seedlings grow quickly, seedlings grow quickly, but it is prone to leggy. In order to cultivate homogeneous and strong seedlings, plastic greenhouse facilities should be used as much as possible for ventilation, cooling and sheltering. When the seedlings grow to 2 leaves and 1 heart, they are transplanted in time.
2, exposed vegetables. Autumn vegetables, autumn celery, autumn potatoes, radishes, spinach, garland chrysanthemum, stem lettuce, etc. sown seedlings or sowing in batches this month. Must choose the appropriate species, pay close attention to soil preparation, good quality. Lettuce and celery are planted from late September to mid-October; green garlic (seedlings) is planted in August until early September; onions are planted in the middle of this month. In addition, fast-growing vegetables, such as young vegetables and spinach, can be sown in batches in batches to ensure the supply of off-season vegetable markets.
Second, after the fall of vegetables, there are mainly solanaceous vegetables and leeks. Solanaceous vegetables mainly include green peppers, eggplants, tomatoes, etc., with many types of production and complex management. At present, the overall growth of vegetables in the field is good, but some of the greenhouses have slow seedling growth and poor growth after planting. The main reasons for this are the thin and thin seedlings that are transplanted. The water absorption capacity is poor, leading to the failure of the stiff seedlings. Poor water management at the seedling stage, poor soil permeability, and hard roots. To this end, field management should be strengthened to promote the growth of vegetables after the current fall, early-onset early-onset seedlings, fast-growing seedlings, mentioning the morning market, and achieving good economic returns. The specific points should be as follows:
1, to strengthen the temperature management into the fall, large temperature difference between day and night, to strengthen the temperature management, in time to increase the temperature of the shed, prevent seedlings and stiff seedlings. Keep 23-28°C during the day to promote vigorous growth of seedlings and keep them at around 15°C at night. When the temperature rises, the amount of ventilation should be increased to prevent leggy.
2. Strengthen the water management to properly control the watering, keep the soil moist, good permeability, and promote the growth of seedling roots, especially transplanting earlier, enter the shed of fruiting buds, to maintain a strong water absorption capacity.
3, to strengthen the application of fertilizer to increase the seedlings poor growth of the greenhouse, appropriate fertilization material to promote seedling growth. The number of specific fertilization varieties should be under the guidance of agricultural technicians, according to local conditions, due to seedlings and appropriate.
4, to strengthen the management of the long-term production of vegetables, green peppers, eggplant, etc. to timely supplement fertilizer material, twigs rake, timely removal of fruit. Autumn tomatoes are generally single stalked pruning, timely removal of excess lateral branches in order to avoid consumption of nutrients. In October, the temperature dropped rapidly. If the number of fruit is too high, the upper part of the fruit will not be able to inflate and only 3-4 spikes will remain.
5, to strengthen the control of locusts, whiteflies: First, timely removal of weeds and old leaves inside and outside, and buried. The second is to use the tropism of locusts and whiteflies to hang yellow plates in rows or between plants in the greenhouse, 20cm above the top of the plants, 30 pieces per 667m2 (40cm50cm) yellow plates, or (30cm40cm) yellow plates 50 Block, and pay attention to timely replacement. The third is chemical control, which is sprayed with 10% imidacloprid wettable powder 1500 times, or 25% pymetrozine wettable powder 3000 times spray. Virus Disease Prevention and Control: At the beginning of onset, spray 20% of virus A WP 500 times, spray 7~10 days, and spray 2~3 times. Nocturnal Pest Control: Noctuid pests are Spodoptera litura and Spodoptera exigua with 20% chlorantraniliprole (Kang) suspension 4000 times, or 600 times the Bacillus thuringiensis suspension, or 1% A 1000 times of salt emulsifiable concentrate, or 6% ethyl spinosad (Aikos) suspension agent 1500 times liquid and other high efficiency and low toxic agent spray control.
Tiger brand electronic safes are made from high-quality materials that are designed to provide maximum security and durability.
The outer shell of the safe is typically made from solid steel, which is known for its strength and resistance to tampering. The steel is often reinforced with additional layers or plates to provide added protection against drilling or cutting attempts.
The door of the safe is equipped with heavy-duty hinges and locking bolts, which are designed to prevent unauthorized access. These locking mechanisms are typically made from hardened steel or other strong metals to ensure that they cannot be easily compromised.
