1994年我局在七套乡郜庄村、小尖镇小广村等地进行蟹、鱼、稻综合养殖高产技术探讨,取得了可喜的成绩。在21公顷面积中,平均每公顷产蟹645公斤,最高产840公斤,鱼种780公斤,稻6105公斤,现将关键技术报告如下:1 稻田改造 选择水源充足,排灌方便,无污染的低洼水田用作稻田养殖。围绕田块四周开挖成宽3—4m,深1—1.2m的环形沟,并在稻田中间设置“+”或“＃”字沟,沟深60—80cm,宽1—1.5m,并在交叉处挖成3—4平方米的小塘。种养面积比例8:2或7:3,将开挖的泥土用来加高加固田
In 1994, our bureau made crab, fish and rice comprehensive high-yield cultivation techniques in seven sets of township villages and townships and Xiaoguang Village in Xiaogan Town, and achieved gratifying results. Among 21 hectares, the average production of crab per hectare is 645 kilograms, the highest yield is 840 kilograms, the fish species is 780 kilograms and the rice is 6105 kilograms. Now the key technical reports are as follows: 1 The transformation of paddy fields selects low-lying paddy fields with sufficient water supply, convenient irrigation and drainage, For paddy farming. Around the field around the block excavation 3-4m wide and 1-1.2m deep annular groove, and in the middle of the paddy field set “+” or “#” groove, ditch depth 60-80cm, width 1-1.5m, and at Crossed at 3-4 square meters dug. Proportion of planting area of 8: 2 or 7: 3, excavation of the earth used to increase the reinforcement of the field
