一、整地 1、栽植密度。耕地退耕还林营造生态林株距2米,行距3米;非耕地河滩大面积集中连片营造速生丰产用材林株距3米,行距4米;“四旁”通风透光条件良好地块可根据具体情况适当密栽。 2、栽植穴规格。长100厘米,宽100厘米,深80厘米。 3、客土与施基肥。好耕地造林栽植,每栽植穴施入腐熟有机肥25公斤,与表土掺均填入坑的底部,上部填入附近的表土。如无有机肥,可每穴施入复合肥1公斤或高效固氮菌肥0.05公斤;河滩沙地造林无表土需要到外部去取土回填,施基肥同上。
First, site preparation 1, planting density. Cultivated land conversion of cultivated land to forest to create ecological forest plant spacing 2 meters, spacing 3 meters; large area of non-cultivated land floodplain contiguous to create fast-growing high yield timber plant spacing 3 meters, spacing 4 meters; “around” good ventilation and light conditions Lot can be specific The situation is appropriate close planting. 2, planting hole specifications. 100 centimeters long, 100 centimeters wide and 80 centimeters deep. 3, guest land and base fertilizer. Cultivation of good arable land planting, applying 25 kilograms of decomposing organic fertilizer per planting hole, with the top soil mixed with filling the bottom of the pit, the upper fill in the nearby topsoil. In the absence of organic fertilizer, 1 kg of compound fertilizer can be applied per hole or 0.05 kg of nitrogen-fixing bacterial fertilizer with high efficiency. There is no topsoil required for afforestation in river beach sand to the outside for soil reclamation and base fertilizer as above.
