Watering tips for tomatoes at different times
The tomatoes have the characteristics of happy water, large water requirement and strong drought tolerance. According to the summary of relevant practical experience, the watering techniques for greenhouse tomatoes are as follows:
Must be watered according to the characteristics of different growth periods. Under normal circumstances, the tomato side of the planting watering, pouring planting water after 3 to 5 days and then pouring a larvae, until the first spike fruit, such as the size of the egg yolk and then poured once. The results of early colonization is smaller, the amount of leaf transpiration is small, the number of fruit is also small, ventilation is also small, usually 7 to 10 days pouring a water (water volume should be small). Later, with the growth and development of the plants, the number of fruits increased, the amount of ventilation increased, and the amount of transpiration increased. The number of days between watering and the amount of watering should be shortened to keep the soil dry and wet (mainly wet) and harvested. The soil should be kept moist to increase the weight of fruit.
According to the characteristics of the watering. Wintering greenhouse cultivation of winter tomatoes, planting period in addition to pouring enough water to planting and timely conservation of cultivators, generally to the first fruit can sit without re-watering, pouring fruit water can be covered with plastic film moisturizing, if necessary Small water is poured under the membrane to avoid lowering the ground temperature. Increase the amount of water after the weather warms to meet the fruit growth and development. Tomatoes grown in greenhouses in early spring should be watered in time to meet their water requirements.
Watering according to growth. The plant is dark green, with shiny, green and flat leaves and stretched heart and leaves. It is a uniform and appropriate expression of water. Such as the heart is not shrinking leaves, dark green leaves, sunny days with mild leaf sagging for the lack of water performance, to timely supply of water. If the leaves are over-expanded, the leaves are large and thin, and the leaves are spewing too much water, which is an expression of excess water.
Watering time in a greenhouse. During the growing season, watering should be done on a sunny day. After watering, it should be ventilated and drained. It should not be watered in the afternoon, evening or rainy days, otherwise it may cause too much humidity in the shed and cause downy mildew and other diseases; it should not be watered at noon. , in order to avoid high temperature watering affecting the root physiological function; late hot weather, greenhouses can stay up late for large ventilation. Water should be used sooner or later to cool down.
Water during fruit harvest. Tomatoes should be watered before they are harvested. This will increase the fruit's commercial value.
Sun-Shading Net is a series of colored shade nets with special optical properties which improve the utilization of solar radiation by agricultural crops. This technology promotes differential stimulation of desirable physiological responses, which determine the commercial value of each crop. This is an economical and environmentally friendly alternative to current labor-consuming methods (such as pruning and thinning) and intensive use of growth regulators and other chemicals. ChromatiNet enables growers to control vegetative growth characteristics, such as leaf size, branch length and plant height in plants, as well as the rate of maturation and flowering. This enables adaptation to market preferences, with clear economic advantages.
Greenhouse Sun-Shading System can reduce solar load, and cool down the inside temperature and create a comfortable environment for the plants.
