Improper fertilization or excessive fertilization can adversely affect vegetable production. Several common types of fertilizers in vegetable growth are:
Dehydration-type fertilizer damage is caused by excessive one-time application of chemical fertilizers, or excessive application of concentrated fertilizer, or insufficient soil moisture. After fertilization, the concentration of fertilizer in the soil is large, which causes the water in the vegetable cells to penetrate into the soil, causing dehydration of the vegetables and often causing the emergence of vegetables. , Like frostbite or boiled water, the light affects the normal growth and development of vegetables, causing death in severe cases.
Fertilizers with burn-related fertilizers, such as ammonium bicarbonate applied at relatively high temperatures, are prone to produce large amounts of ammonia, burn vegetable leaves, light yellow leaves on the lower part of the vegetables, and heavy plants with yellowish rot. In some sheds, the application of uncooked chicken manure can also lead to burning of roots and burning of seedlings.
Toxic fertilizers Some fertilizers, such as lime nitrogen, can be transformed in the soil if applied improperly (direct application). During the decomposition process, a toxic substance is produced that poisons the roots of the vegetables.
In order to ensure that vegetables and their roots are not harmed by fertilizers, but also to maximize soil fertility and promote the lush growth of vegetables to obtain high yields, we must pay attention to balanced fertilization. Balanced fertilization means that all plants of a crop can absorb various nutrients required for robust growth in a certain proportion and quantity. At the same time, it also means that the nutrients obtained from the soil in the crops are returned to the soil nutrients by fertilization, air, and water, so that the crops are both high in yield and the soil is not compacted.
Glass Venlo Greenhouse is Spire-type glass design, design and installation of windows when more convenient and easy. Its roof slope andle can be appropriately according to the local real climate change the environment.
In Venlo greenhouse, foundation is made of reinforced concrete and the side wall is made of brick or reinforced concrete plate. the steel frame always use hot dip galvanized light steel. Roof beam adopts horizontal girder structure and using herringbone connection. The horizontal girder bears 2 or more roofs, which is made of aluminum alloy. This material is used as roof structure material and also glass inlay material. Other beams using gutter style to minimize the section. Delighting material of the roof and side wall using 4 mm thick float glass.
