I. Environmental Requirements for Green Onion Cultivation: 1. Temperature: Green onions are cold-tolerant crops, with seeds capable of germinating at temperatures between 2°C and 5°C. The optimum temperature for growth is between 15°C and 25°C, while temperatures exceeding 30°C slow down growth. Exposure to temperatures of 0°C to 3°C for 7 days or 3°C to…
In winter, watering greenhouse vegetables should be scheduled on sunny days, preferably with several consecutive sunny days following irrigation. It’s best to choose the morning for irrigation as there’s minimal temperature difference between the water and soil, and the soil temperature can recover quickly.
Greenhouse and tunnel cultivation with drip irrigation technology is considered an essential pathway for the modernization of agricultural production, offering significant advantages. However, there are several challenges currently facing the development of drip irrigation in greenhouse cultivation, including issues related to planning and design, equipment quality, and management practices. Addressing these challenges is crucial for…
Drip irrigation is a precise irrigation method that utilizes low-pressure pipeline systems to deliver water directly to fields. Through the use of drippers, outlets, or drip irrigation tapes installed on capillary tubes, water is slowly and evenly dripped into the soil near the crop roots.
Heat damage often accompanies drought stress, particularly during the hot summer and autumn seasons. Young organs and tissues are particularly susceptible to heat damage. Symptoms include brown patches from sunburn on rolled leaves, yellowing leaf margins resembling “gold edges,” chlorosis near the midrib turning yellow-white, cessation of root growth, and bud-bearing plants with fewer green…
Drip irrigation in citrus orchards refers to the supply of irrigation water to the soil in the root zone of citrus trees through hoses at low pressure and low flow rate, in the form of intermittent drip irrigation. It is the best irrigation method for citrus orchards. Compared with traditional irrigation, what are the advantages of…
There are many types of vegetables, with different cultivation methods and cultivation periods, as well as different climate conditions in different places. A variety of irrigation methods must be used to meet the requirements. This article briefly introduces common vegetable irrigation methods. Vegetable irrigation includes surface irrigation, underground irrigation and above-ground irrigation. 1. Ground irrigation…
Irrigation for greenhouse vegetables has gradually transitioned away from flood irrigation methods. With increasing demands for vegetable quality and disease reduction, micro-irrigation technologies have become the mainstream in greenhouse vegetable production. Below are several common and water-saving new techniques for greenhouse vegetable cultivation.
Yield Index: First year after planting: Fruit-bearing begins. Second year: Achieve a yield of 500-800 kg per 666.7 square meters (mu). Peak fruiting period: Yield reaches 2500 kg. I. Variety Selection: Considerations: Quality, disease resistance, storage tolerance, and adaptability to local climate and geography. Criteria: Opt for established varieties, promising new cultivars, and a balanced…
Introduction: Traditional irrigation methods for grape production, such as manual watering and furrow irrigation, are characterized by low water use efficiency, labor-intensive operations, poor irrigation quality, and limited support for high-quality, high-yield crops. With increasing water scarcity due to regional, seasonal, and resource-related factors, the need to adopt advanced, efficient water-saving irrigation technologies in grape…
