What methods are there to improve the fertilizer uptake rate of bitter melon?
How can bitter melon be managed to achieve a high yield? Please advise: for seed soaking and sprouting, select early- and mid-maturing large bitter melon varieties with vigorous growth, strong fruiting capacity, plump bodies, and fruit length over 25 cm, and mix the seeds with New High-Fat Film (can be mixed with seed treatment agents or pesticides), which can repel underground pests and diseases, isolate viral contamination, and strengthen seed respiration...
How can the fertilizer uptake rate of bitter melon be improved? Please adviseAt present, the topdressing method commonly used by vegetable growers planting bitter melon is applying fertilizer washed in with irrigation water. Although this is very convenient and can evenly apply fertilizer into the soil, this topdressing method is not advisable. The reason is that bitter melon is planted at a relatively low density, with only 200-300 plants per mu and only 3-6 plants per row. If topdressing is done by washing fertilizer in with irrigation water, the fertilizer utilization rate will be very low and the waste will be serious.
Therefore, vegetable growers are reminded: topdressing for bitter melon should be changed to concentrated fertilization, such as digging ring-shaped trenches for fertilization, which can greatly improve the fertilizer utilization rate. The specific method is to dig a ring-shaped trench 20 cm inside the bitter melon plant, with a trench depth of 5 cm, then apply 50 g of compound fertilizer or 80 g of biological fertilizer per trench, cover the trench with soil, and then water. Alternatively, dig a strip trench half a meter long 20 cm inside the bitter melon plant, and apply the above amount of fertilizer per trench; the effect is also quite good. It should be noted that after each topdressing of bitter melon, water should be applied promptly, so that the absorption effect is better.
