[0027] 1) Soil preparation and base fertilizer application, 50kg of slow-release fertilizer with nitrogen, phosphorus and potassium content per mu is used as seed fertilizer;
[0028] 2) Select dense-resistant good varieties, sow early at the right time, and coat the seeds before sowing. The seed coating agent is prepared from 2.5% fludioxonil, 1% metalaxyl, 30% thiamethoxam and the rest of water , using the wide-row and narrow-width staggered dense sowing method, the wide row is 70cm, the narrow row is 30-40cm, the plant spacing is 18-21cm, and the staggered vertical spacing between adjacent rows is staggered. The corresponding vertical spacing between rows is plant spacing / 2;
[0029] 3) For chemical control weeding, spray pendimethalin 1-2 days after sowing and post-emergence at a dosage of 200ml / mu, and spray nicotinic acid and atrazine at the 3-5 leaf stage at a dosage of 200ml / mu to inhibit weeds. grass growth;
[0030] 4) Chemical control to help the strengthening, spr...
