1.小麦疏株密植播种机该机适用于砂田、旱地、坡地、丘陵地的人力机播小麦作业,行距、播深可调, 1人操作。试验表明:①种子分布均匀,播量准确,播深一致,横成窝、纵成行,出苗整齐。②出苗率高,通风透光好, 苗壮穗大,成穗多,不易倒伏。据测定,机播与人工铲行条播相比,有效穗数平均每亩增加4.08万;穗粒数增加2.95;千粒重增加0.8克;每亩平均增产10.9～27.9%。⑧操作简单,省工,省种。该机体积小,重量轻,中等劳力每天可播4亩,一次作业可完成开沟、播种、覆土,每亩节约种子1.5千克。每台参考售
1. Wheat sparsely planted seeding machine This machine is suitable for field work in dry land, dry land, sloping land and hilly land. The spacing and depth of sowing are adjustable and 1 person operates. Tests showed that: ① seed evenly distributed, sowing accuracy, sowing depth consistent horizontal nest, vertical line, emergence and tidy. ② high germination rate, good ventilation, seedlings spike large, into more than spike, not easy to lodging. It has been determined that, compared with artificial shoveling, the effective spikes increased by 40,800 per acre; the number of grains per spike increased by 2.95; the weight per thousand increased by 0.8 grams; and the average yield per acre increased by 10.9-27.9%. ⑧ simple operation, labor, provincial species. This machine is small in size and light in weight. Medium labor force can broadcast 4 mu per day. One operation can finish ditching, sowing and covering soil, and save 1.5 kg of seed per acre.
