Planting matters and water and fertilizer management of bitter gourd in early spring
Bitter gourd has the effect of clearing heat and dispelling fire. Many people like to eat, especially by girls. The season when bitter gourd is listed in large quantities is summer and autumn. When it is listed, the demand is large. Many farmers will choose to plant. Now, when is the bitter gourd planted in early spring? What are the main points of water and fertilizer management? First, the planting time In early spring, bitter gourd can be cultivated in a solar greenhouse or a greenhouse. Because of the early spring, the bitter gourd seedlings are in the low temperature and low light period, and the seedling age is long, generally 55-60 days old. According to the situation of each region and the cultivation structure, after the planting period is determined, the seedling raising time can be advanced. For example, in the Yellow River Basin, the early spring bitter gourd in the solar greenhouse can be planted in mid-February, generally in the middle of December last year. Large arch shed planting can be planted in mid-March, and farmers are better at mid-January. After the early spring, the temperature gradually warmed up and gradually adapted to the growth of bitter gourd. Although the growth period did not last longer, but in various conditions, the peak of production came early, generally in the period of April-May. The market gap is large, the price is high, and the economic benefits are better. Second, water and fertilizer management In early spring, bitter gourd grows fast, and nutrients are consumed. In the middle and late stages, the temperature is high, the leaf area is getting larger and larger, and the transpiration is very strong. In order to meet the requirements of water and fertilizer for plant growth and development, it is necessary to grasp the management of water and fertilizer. 1, watering management When the bitter gourd is planted, it will be planted with water, and the water is generally controlled for 10-15 days during the period of vines to prevent the vegetative growth rate from being too fast. When the flowering result period is entered after about 15 days, in order to promote fruit growth, watering should be done in time. When the bitter gourd is watered, master the "pour the fruit without watering the flowers" and the small water to pour water to prevent flooding. When the flowering period is not dry, it will not be watered. When the fruit is placed, it should be poured with small water to prevent soil compaction caused by flooding, and the permeability is poor, which affects the absorption capacity of the root system. 2. Fertilization management Each time watering should be combined with top dressing. As a result of bitter gourd, the outside temperature is low in the early stage, and the farmers should cultivate the roots of the vines. The low-content compound fertilizer with high humic acid should be applied with the water; the external temperature should be warmed during the fruiting period, and the nitrogen fertilizer should be applied. . As a result, the early stage yield is low, and the consumption of nutrients is small. It is recommended to apply about 15 kg of humic acid-based water-soluble fertilizer per acre. Or apply 1-2 times of heavy fertilizer in the stem and vine prosperous growth period and flowering result period, apply 25-30 kg of compound fertilizer per acre. After entering the fruiting period, when the plant needs a large amount of nutrients, the amount of fertilization can be increased. Generally, 30 kg of ammonium nitrate-based nitrogen fertilizer is applied per acre. After 2-3 consecutive strokes, it is recommended to apply about 35 kg of compound fertilizer per acre or 300 kg of human excrement. In the later stage of the results, the roots of the plants are aging, and the absorption capacity is deteriorated. When the amount of planting seeds begins to decrease, it is necessary to reduce the number of watering and reduce the amount of fertilizer. It is recommended that the average acreage be applied for 10-15 kg of fertilizer per acre. The above is the planting and water and fertilizer management of bitter gourd in early spring. Planting early spring and bitter gourd must master the planting time and management of water and fertilizer. This is the key to high yield and high yield of bitter gourd. Moreover, the bitter gourd at this time is very popular, and the market demand is relatively large. The growers can consider planting.
