为了尽快把农业生产搞上去,重点介绍几种低产田的改良办法,供各地冬天大搞农田基本建设时参考。(一)夹泥田改良夹泥田(包括红夹泥、黄夹泥、白夹泥、胶质泥)主要分布在丘陵地带的坡山脚、高岸田以及地势平坦、水利条件较好的垄田。它的特点是:土质细腻,粘性大,通透性不良。湿时粘重,干时板结坚硬,犁耙困难。群众曾有这样的说法:“天晴一把刀,下雨一团糟。”这类田耕作层浅,一般只有4寸左右,机耕过的也有6～7寸。保水保肥力强,土壤带微酸性或中性,有机质、养分含量中等。由于土粘通气性差,养分分解缓慢,有效养分少,禾苗转青
In order to start the agricultural production as soon as possible, we will focus on introducing several improved methods for low-yielding fields for reference when capitalizing on farmland in winter. (A) folder muddy field modified folder mud field (including red folder mud, yellow folder mud, white folder mud, gummy mud) are mainly distributed in the hilly areas of the foot of the hill slope, high bank and flat topography, favorable water conditions ridge fields. It is characterized by: delicate soil, sticky, poor permeability. Sticky when wet, hard when hardened, rake difficulties. The masses had this saying: “fine a knife, it is a mess.” This type of field tillage shallow, generally only about 4 inches, plowed there are 6 to 7 inches. Water and fertility, soil with slightly acidic or neutral, organic matter, medium nutrient content. Due to the poor adhesion of soil, nutrient decomposition slow, less effective nutrients, seedlings turn green
