Suitable planting time, regions and cultivation techniques for ginger
Abstract. Site selection and fertilization: choose soil with a deep plow layer, loose and fertile texture, and rich in organic matter, and apply rotted organic fertilizer and compound fertilizer as a base fertilizer. Seed selection and sprouting: choose 1-2 ginger pieces as seed, then soak them in a 500-fold dilution of 50% carbendazim for disinfection. Sowing time: the suitable sowing time is from the end of April to the beginning of May. Fertilization and watering: during the growing period, ammonium sulfate, cake fertilizer and compound fertilizer can be applied, and the soil moisture content should be kept at 75%-80%.

When Is the Right Time to Apply Growth Control to Sweet Potatoes? A Detailed Guide to Timing and Techniques
Abstract The first growth control application is during the sweet potato's swelling stage; the second growth control application is around 65-70 days after planting; the third growth control application is around 85-90 days after planting. Generally, growth control can be achieved by lifting the vines, cutting the vines, or using chemicals. Among these, cutting the vines not only effectively controls excessive vine growth but also provides sweet potato vines for feeding pigs, which helps save on feed costs.

When is the right time to apply potassium fertilizer to rice
Abstract The suitable times for applying potassium fertilizer to rice are the tillering stage, the young panicle differentiation stage and the booting stage. Applying potassium fertilizer at these three stages can effectively increase the seed-setting rate of rice, reduce pest and disease damage and increase yield. Combined application with phosphate fertilizer and nitrogen fertilizer can give full play to the effectiveness of potassium topdressing, among which the ratio of nitrogen, phosphorus and potassium is preferably 1 : 0.5: 1.2.

When is the best time to bag and unbag grapes
Abstract Grape bagging time: For open-field cultivated grapes in southern regions, bagging can be done promptly after fruit set following cluster trimming and berry thinning; while for greenhouse and rain-shelter cultivated grapes, bagging can be done 15-20 days after fruit set. Grape unbagging time: With traditional bagging, bags can be removed 10-15 days before harvest.
