(1) Early Transplanting Stage
The second crop rice transplanted to the field is in the hot summer season, in order to cooperate with the application of herbicides, irrigation should maintain a water depth of around 3cm within the first five days after transplanting, while flood irrigation can be employed to lower water temperature and promote early tillering. This can help reduce the hot damage on young seedlings during this period.
(2) Vegetative Stage
Early tillering stage
Proper top-dressing during this stage can help tiller development effectively and enhances plant healthy. The first top-dressing is applied 7-10 days after transplanting, consisting of 20% nitrogen to support rapid growth during early tillering, it’s recommended to use Go Sprout 131 (Special for lateral budding) to promote root system growth and tillering.
Mid-late tillering stage
15-20 days after transplanting, it’s time to apply second top-dressing fertilizer. Providing 30% nitrogen and 40% potassium to replenish the nutrients that large use during the tillering stage. It’s recommended to use Si Force 851 (Special for Poaceae, High in Silicon and Calcium).
Water-soluble silicon, lignin, and EDTA-Ca content thickens the cell walls of plants, enhancing the crop ability to stand upright and resist lodging. Silicon can enhance the plant stress resistance. Molybdenum can promote flower bud differentiation, preparing for panicle differentiation. When using antioxidants such as vitamin C and glutathione ensures antioxidant function of the plant and enhancing plant tolerance to the stress.
(3) Reproductive Stage
During the panicle initiation stage, a proper amount of Nitrogen top-dressing during panicle stage can increase the grain number, fertility rate, and a thousand grain weight. Providing 20% nitrogen and 20% potassium 40-45 days after transplanting. It’s recommended to use the foliar fertilizer mix of Si Force 851 (Special for Poaceae, High in Silicon and Calcium) and Ca Strong 801 (Special for Water Retention), this can aid rice in its reproductive growth stage, requiring deep irrigation (5-10 centimeters), while simultaneously facing the adversity of drought conditions in the central and southern Taiwan.
Ca Strong 801 contains appropriate amounts of nutrients and elements, silicon and sugar can enhance plant water retention; high potassium, high calcium, and fulvic acid can help regulate plant stomata; nucleotides can slow the plants senescence; betaine can regulate cell walls and prevent dehydration.
Second crop rice cultivation often encounters typhoons and heavy rainfall. Enhanced field drainage is necessary to prevent lodging and excessive water in the field cause the sprouting at the panicle, which can affect grain quality. Additionally, monitoring and pest management are must to do after a typhoon. Extra foliar feeding is the best way to quickly replenish nutrients and assist crops in overcoming the growth stress.
