The cultivation of green beans has been around for 35 days and has entered the flowering stage. At present, according to the problems in production, the following management measures are proposed for the reference of the majority of green bean growers:
1. When flowering and scabbing, reapply once attacking manure: Acres topdressing compound fertilizer 20-25kg and urea 5-8kg. In buds, early flowering stages, and early stage of pods, foliar spraying with 0.1% urea + 0.2% potassium dihydrogen phosphate + 0.1% borax was applied 2-4 times to promote flowering and scab, and increase yield and product quality.
2. Control of pests and diseases: Since this time, whitefly has begun to occur, and 10% imidacloprid wettable powder 1500 to 2000 times liquid or 10% acetamiprid microemulsion 2000 to 3000 times liquid can be used for alternate spray control. At the same time, as the temperature rises and the rainy season approaches, prevention and control of rust, root rot, and powdery mildew are done at all times. Its control methods: 1 rust, powdery mildew 20% myclobutanil microemulsion 2000-3000 times or 20% difenoconazole (Jetella) 4000-6000 times spray or 43% tebuconazole 3000 times spray. 2 root rot: While strengthening the water management, use 75% chlorothalonil wettable powder 600 to 800 times liquid spray root or rooting prevention.
3. Manual removal of weeds: With the advent of the rainy season, green beans grow rapidly, weeds and beans conquer water, compete for fertilizer, and manually remove weeds, creating a good environment for the growth of green beans.
4, timely harvest: 15 days after flowering can be harvested. When the pods grow to about 15cm, the glutinous rice cakes are harvested within the range of 0.6cm in time, and the timely harvesting of beneficial nutrients is transferred into the growth of new pods to increase the total output. After harvesting, it will be sold in time, and if it is stored for too long, it will be discolored and deteriorated, lose the value of commodities, and reduce the output and output value.
