一、稻田水网的危害稻田水网(Hydrodictyon reticulatu-m)是绿球藻目的一种,藻类,群众称“青苔”。信阳地区稻田普遍发生,严重田块水网如同绿色棉絮充滞田间,尤在5月中旬至6月中旬,正值春稻栽秧,返青分蘖时期,水网大量繁殖,纠结缠绕秧苗,遮蔽阳光,降低水温,严重影响水稻生长发育;同时又不便于田间农事操作,降低农活质量。水网实为水稻田的一大“杂草”。
First, the hazards of paddy water network Paddy water network (Hydrodictyon reticulatu-m) is a Chlorococcaceae purpose, algae, the masses called “moss.” In the Xinyang area, rice fields generally occur. The serious water network in the fields is like green cotton filled fields, especially in mid-May to mid-June, when the spring rice is planted and the greening tillering stage occurs. The water network multiplies and tangled the seedlings and shields the sunlight , Reduce the water temperature, seriously affect the growth and development of rice; at the same time it is not convenient for agricultural operations in the field and reduce the quality of agricultural work. The water network is actually a big “weed” in paddy fields.
