福安市是我省的北缘蔗区,背山靠海,气候温和,雨量充沛,适宜甘蔗生长。近几年,由于种蔗对比效益明显下降,蔗农积极性受到挫伤,致使植蔗面积逐渐萎缩。基于这种状况,为了提高种蔗的经济效益,我站近几年来在蔗园间套种植、搞好综合利用方面进行初步的探索,取得了一定的成效。我市利用无霜期短,前期气温回升慢,后期寒流来临早的特点,采用地膜覆盖、品种选择、合理确定植期等方式,筛选了一批适合闽东发展的蔗田间套种方式,以供参照。 一、栽培模式 1.茄子+糖蔗:茄子立冬播种,地膜覆盖,惊蛰定植。糖蔗2月地膜覆盖,春季育苗,清明定植,每公顷产糖90吨,茄子180吨,总产值2.4万元,纯收入1.095万元;比单种植蔗每公顷产糖75吨,产值1.125万元,纯收入0.27万元,分别增加1.275万元和0.825万元。 2.莆豆8008+糖蔗:莆豆8008秋季繁种,3月下旬前直播,糖蔗春季育苗,清明定植。每公顷产糖蔗82.5吨,莆豆1.125吨,总产值1.545万元,纯收入0.63万元;比单种糖蔗每公顷产
Fuan City is the northern sugarcane area in our province, backed by the sea, a mild climate, abundant rainfall, suitable for the growth of sugar cane. In recent years, due to the significant decrease in the comparative benefits of seed cane, the enthusiasm of cane farmers was dampened, causing the area of cane sugarcane to shrink gradually. Based on this situation, in order to improve the economic benefits of seed cane, I stand in recent years in the cane plantations, do a good job of comprehensive utilization of the initial exploration and achieved some success. The city screened a batch of sugarcane intercropping methods suitable for the development of eastern Fujian for the reference by using the features of short frost-free period, slow temperature rise in the early period and early cold weather in the late period. First, the cultivation mode 1. Eggplant + sugar cane: Eggplant winter planting, plastic cover, Jingzheng colonization. Sugar cane in February mulching, seedling cultivation in spring, planting clear, planting, producing 90 tons of sugar per hectare, 180 tons of eggplant, the output value of 24000 yuan, net income of 109500 yuan; than single sugarcane sugar production 75 tons per hectare, the output value of 11.25 million Yuan, net income of 27,000 yuan, respectively, an increase of 12,750 yuan and 0.825 million. 2. Putian 8008 + sugar cane: 8008 Pujiang autumn variety, live before the end of March, sugar cane spring nursery, planting clear. 82.5 tons of sugar cane per hectare, 1.125 tons of bean, total output value 154500 yuan, net income of 06300 yuan; than single sugar cane per hectare production
