Autumn and winter crop cultivation points

Autumn and winter crops are an important part of agricultural production in Shidian County. The main source of farmers' income and the management of winter crops are the main means to achieve single yield, product quality and comprehensive benefits.

 

First, rape

 

   1. Formulated fertilization: 25 kg of urea is applied to the fertilization of the fertilizer, and the fertilizer is applied with 10 kg of urea , 5 kg of potassium sulfate, and 5 kg of potassium sulfate . The flowering and pod-forming period is 200 g of potassium dihydrogen phosphate, 100 g of borax with water 50 kg of spray 2 -3 times.

 

   2 , strengthen management: 15 days after sowing, the first seedlings were carried out, and too many dense seedlings were removed, leaving 4-5 strains per pond . The second seedling in the 4-5 leaf stage, leaving 2-3 seedlings per pond . 5-6 leaf stage acre with 15% paclobutrazol 30-50g water to enhance its resistance. After sowing, timely watering for seedling emergence, 5-6 leaf stage, bud stage, flowering and pod-forming period.

 

   3 , do a good job in the integrated control of pests and weeds: 25-30 days after sowing , the use of rapeseed special herbicide "Fu Liduo" or "Xianqi" 30g water 20-30kg spray to prevent weeds. Insect pests were sprayed 2-3 times with "acetamidime" or "imidacloprid" 1000 times solution . The disease is sprayed with 70% methyl thiophanate or 20% triadimefon emulsifiable concentrate 1000-1500 times solution or 30% Dehui ( tebuconazole) 1500-2000 times solution, once every 7-10 days, continuous 2- 3 times, pesticides can be used interchangeably.

 

Second, wheat

 

   1, rational fertilization: the early tillering, at the three-leaf stage Mushi urea 15-20kg, Shi good jointing fertilizer, according to Miao potential in the jointing stage Mushi urea 10-15kg, of applied fertilizer, flowering to filling stage acres It was sprayed with water of 200 g of potassium dihydrogen phosphate for 2-3 times.

 

   2 , chemical weeding: two leaves one heart weeding once, the use of Hummer ( fine oxazole grass ) 40-50ml or benzenesulfuron 15g water 25-30kg spray.

 

   3 , do a good job of pest control: from flowering to filling stage with 20% triadimefon emulsifiable concentrate 1000-1500 times liquid to control wheat rust and powdery mildew 2-3 times, with acetamiprid control mites 2-3 times, sheath blight in After jointing, control with tebuconazole for 1-2 times.

 

   4 , chemical regulation: wheat seedlings to three to four leaves and before the jointing with paclobutrazol once increased the stress resistance.

 

Third, broad beans

 

   1 , early topdressing: When the seedlings 5-6 pieces of true leaves, the use of manure excrement 5 to add potassium sulfate or potassium chloride 5-7kg , poured with water.

 

   2 , pruning topping: the top of the branch when the pod is topped.

 

   3 , spraying foliar fertilizer: flowering to pod-forming period with 200g of potassium dihydrogen phosphate, 40-50kg of water spray 2 times.

 

   4 , prevention of pests and diseases: flowering to the filling stage disease with 15% triadimefon, 50% carbendazim, 30% Dehui ( tebuconazole) 1000-1500 times liquid control. Insect pests were controlled with 10% imidacloprid, 10% cypermethrin and the like.

 

Fourth, green manure

 

   1. Open the three ditch: timely discharge, no water after the rain.

 

   2, increasing nitrogen phosphorus: Before the winter topdressing superphosphate per acre 15-20kg.

 

   3 , timely pressing: mastering 7-10 days before transplanting in Daejeon is better.
