Causes of Dead Seedlings of Vegetables and Preventive Measures
There are five main reasons for the death of vegetable seedlings after seedlings. First, the soil temperature of the seedbed is too low. After the seedlings reach the seedbed, they can't take root and cause dead seedlings. Second, the seedling soil mixes in the unconsolidated organic fertilizer unevenly. Caused burning root dead seedlings; Third, when the seedlings are too often raised, not enough time to make the seedlings lose water too much, it is not easy to recover and die after splitting; Fourth, the seedlings before the seedlings development is not good, less root; It is because the seedlings are too late, causing the roots to be damaged, and the absorptive capacity is weak and dead. In summary, the following comprehensive measures shall be taken to prevent and control the death of seedlings after sub-seedling: 1. Raise soil temperature in seedbed to ensure seedling temperature requirements after seedlings. Seed bed soil temperature such as cucumber and eggplant is not lower than 16°C. 2, the use of organic fertilizer seedbed soil must be fully fermented maturity, and carefully mixed with the bed soil. When the seedlings are divided, the bed soil shall be compacted and leveled, then ditched, placed in seedlings, and watered, and the soil shall be sealed after the water infiltration. Then move into the nutrient pods. 3, when the seedlings do not hurt too much root, and more with some of the soil, with the points, do not raise too much time. Remove the seedlings with a damp cloth to prevent excessive water loss. In the process of raising seedlings, we also need to pick out seedlings with few roots, broken leaves, sickness and deformity. It is not advisable to divide the seedlings into small ones to improve the survival rate. Usually the first time the seedlings are divided, when the seedlings of Solanaceae grow in two leaves, the cucumber seedlings are before the cotyledon is unfolded. Sub-seedlings should be selected for sunny days, such as when greenhouses have high light intensity, they can be placed above the sheds and shaded by a grasshopper at a certain distance to prevent direct sunlight from reaching the seedlings that have just finished. Greenhouse Drip Irrigation System Fertigation is using your irrigator to fertilise the plants and soils as you water, which is the most efficient and advanced practice of fertilization. Aid of pressure system (or natural divide terrain), the soluble solid or liquid fertilizer, according to the soil nutrient content and crop fertilizer regularity and characteristics of species, with the fat of with irrigation water, through a controlled water supply pipeline system, supplying, the compatibility, water through the pipe and drop head form drip irrigation, uniform, regular, quantitative, infiltration area crop root growth and development, make the main root soil always stay loose and appropriate moisture content, at the same time according to different crop fertilizer characteristics, environment and soil nutrient content in soil; Crops in different growth phase water requirement, the different development stages of the fertilizer rule is the demand of design, the water and nutrient timing quantitative, provided directly in proportion to the crops.
