On 30 march, journalists were informed by the municipal centre for agricultural technology services that, in response to the current demand for spring farming production and disease prevention and control, the agricultural technology service of our city has recently been targeting a large number of farmers and actively engaged in the promotion of solar greenhouses, plastic sheds, open spring vegetable cultivation techniques, with a view to boosting farmers' incomes through a variety of means, such as “north rye south” and the international market for exports, in order to ensure the livelihood of local citizens. It is planned that the total area of vegetable planting will reach approximately 270,000 acres throughout the city this year, with facilities (including solar greenhouses, plastic sheds) covering approximately 25 per cent of the total area under vegetable cultivation throughout the city。
According to municipal agricultural experts, with regard to the management of vegetables in the solar greenhouse spring, we now have winter tomatoes and cucumbers entering the flowering season, and green vegetables such as artemisinin, cabbage and cuisine entering the boom, with a focus on strengthening temperature, light, water fertilisation and pest control. During the daytime, suitable temperatures range from 25 °c to 30 °c and at night from 15 °c to 20 °c. Farmers are required to take measures such as temporary heating, lighting and greenhouse ventilation in the light of weather changes. In order to ensure the maturity of the vegetables, farmers are able to round up and remove the leaves, improve the light conditions of their crops, introduce supplementary pollination measures for tomatoes and cucumbers during the flowering period to promote fruit growth, implement integrated irrigation of hydrofertilizers, use a variety of techniques, such as agricultural control, ecological control, biological control, physical control, etc., to address the problems of vegetable pests and pests, and collect them in a timely manner in such a way as to ensure that they are tender and well-looking。
With regard to the management of plastic sheds for spring vegetables, the technical focus of vegetable breeding is to improve the temperature protection of the plastic sheds, to cultivate strong seedlings and to plant them as early as possible, and to ensure that the temperature in the night sheds is not less than 13°c. Increased ventilation in the plastic shed 7 to 10 days before the planting of a vegetable seedling, control of water recharge, gradual removal of the cover, low-temperature seedlings and choice of a clear and windless morning planting of a vegetable seedling。
With regard to the management of vegetables in the open spring, our city's winter vegetables consist mainly of spinach, onions and so forth. In the near future, farmers have to clear the weeds in their vegetable fields, catch up on the occasion of weather and water, and promote the early return of vegetables to the market. In april, our city planted direct vegetables such as garlic, cabbage, oilseeds and other cold-resistant vegetables in the open. Farmers were required to fertilize in a timely manner, so that seeds could be sterilized before planting, and pests and pests could be prevented and mitigated。
