In order to ensure the maximum benefit of the land, we often carry out the interplanting planting mode, and the interplanting can not be casually set, and the vegetable variety should be selected. So which vegetables can be interplanted? Let's take a look at the intercropping pattern between potatoes, corn and spinach. 1, spring potato Choose Fabri, Dutch potato, medium potato or other detoxified potato. Applying 2000-2500 kg of organic fertilizer per acre and 50 kg of 45% potassium sulfate compound fertilizer, the whole land is made of sorghum, and the width is 4 meters. Sowing around February 20, each line is broadcast 8 lines, the hole distance is 20 cm, and about 6,000 holes per acre. Cover the film to increase temperature after sowing. After emergence, the seedlings were ruptured in the middle and late March. Before the potato is budd, it is generally necessary to apply early topdressing according to the growth of the vegetable plant. First, a 10 cm deep cave is placed 10 cm away from the plant, and then 7.5-10 kg of urea is applied to one mu, and 1% urea solution is sprayed at the same time. And 0.5% potassium dihydrogen phosphate solution. At the flowering stage, attention should be paid to the control of diseases and insect pests such as late blight and aphids. Spring potatoes are harvested in late May. 2, fresh spring corn Choose Zhenghei No.1, Zhengbaiyu No.6, Special Sweet No.1, Huyuyu and other varieties. From the end of March to the beginning of April, a row of spring corn was planted in the spring potato ditch, the sowing depth was 3 cm, and about 1800 seedlings per acre. Cover the fine soil after sowing. From the end of April to mid-May, due to the early application of fertilizer and panicle fertilizer, the use of low-toxic, low-residue pesticides in the big bell mouth to control corn mash and fresh spring corn was harvested at the beginning of August. 3, summer corn Choose the Zhengdan 958 variety with compact plant type. Generally, at the end of May, after the potato harvest is completed, we can plant 2 rows of summer corn in the middle of the sorghum. The spacing between the corn is 50cm, and the distance between summer corn and spring corn is 1.75 meters, and the seedlings per acre are about 25002500 plants. 40-50 kg of corn special fertilizer per mu before sowing, and 15-20 kg of urea per acre at the jointing and booting stage. Focus on prevention and control of corn spot disease, small spot disease, sheath blight and corn borer diseases and insect pests. Summer corn is harvested from the end of September to the beginning of October. 4, autumn potato Choose Dongnong 303, Zhongshu series and other varieties. First of all, we must plant the seed potatoes in a cool, humid, ventilated and sheltered room in advance, and lay a layer of 5 cm thick wet sand on the ground of the germination room, then discharge the seed potatoes on top, and then cover the wet sand. This is a layer of wet sand layer of potato and phase emissions, generally 2-3 layers, the top layer should be covered with wet straw, so as to ensure the low temperature and humidity of the potato pile, and then wait until the seed potato germination. From mid-late August to early September, 8 rows of corn were planted between the corn rows, and 5500-6000 holes were planted per acre. Before the sowing, apply 2000-2500 kg of organic fertilizer per acre, 40-50 kg of ternary compound fertilizer; apply 10 kg of urea per mu after the seedling; see the seedlings to apply tuber swelling fertilizer, mainly potassium fertilizer; after the plant is sealed top dressing. After sowing, the surface is covered with straw or wheat straw, and the shade net can be covered conditionally. After emergence, combined with fertilization, weeding, soil removal, and clearing ditch. The main disease of autumn potato is late blight. It can be sprayed with 64% anti-virus cockroach 500 times before the plant is sealed. It should be sprayed once every other week for 2-3 times. If it is autumn potato, it is basically taken in early November. Received. 5, autumn sowing spinach First of all, we must use spinach varieties with strong cold resistance, and we should promptly broadcast spinach after harvesting autumn potatoes. The above is the introduction of the vegetable planting model. Of course, in addition to the above vegetables, there are many vegetables that can be planted in the interplanting. When it comes to this, Xiaobian wants to ask you what kind of vegetable interplanting mode?
