Deficiency occurs less corn planter job seedlings phenomenon, Seedmeter test Seeding uniform and did not find fault, fertilizer and maize seed also shifted away from this situation, but also what is the reason? A: Yes, because the fields have clods, down corn planter when seeding, seeding opener Lou leg stuck clods, corn seed fell on the clods can not be sown to corn planter good quality ground, resulting in Deficiency or a rope no seedlings, seedlings appear sparse because it is on the accumulation of excessive clods falling down some corn buried in the earth, some on the surface, so there have sparse or simply non-Miao Miao, sometimes when You lift corn planter is able to detect lumps, as it has been dropped, and the you do not find in our corn planting must pay attention. Prepare corn planter in front of the job: 1, selection: maize varieties have different options for soil fertility and other conditions, depending on the variety. Corn planter is a precision sowing, planting distance can be adjusted according to needs, normally spacing of 40cm to follow the instructions on the seed corn to decide, generally close planting spacing should be about 30cm, seed particles to choose full, high-quality seed corn planter germination rate ninety-five% or more, and seed coating treatment. 2. Select fat: The machine should be used in granule fertilizers (urea, ammonium sulfate, fertilizer, etc.) of powdered fertilizer easy caking, poor mobility will affect the fertilization effect. Particle fertilizer before planting new corn planter needs to be checked, to remove lumps to avoid blocking the tube fertilization amount of fertilizer, fertilizer per acre 5-10kg appropriate. 3, seeding: corn planter can once completed stubble, ditching, seeding, fertilizing and other working process, when seeding, the seeds should be sown in the soil depth 5cm deep, fertilizer should be applied to the soil 8cm deep, kind of fat Split - not less than 4cm. Not leak broadcast, not replay, consistent sowing depth corn planter video, well casing, repression tight. 4, timely spraying: timely and appropriate spraying chemical herbicides and insecticides to be sprayed with herbicide-time within three days after sowing, also at 3 leaf stage of weed weeding of "off-type" herbicide ( spraying again within 12 hours after the rain).
