1. Pay attention to the timely spraying of paclobutrazol: after the peanut blooms to the beginning of the lower tip, spray paclobutraz in time, the effect of increasing yield is significant, up to 15% to 20%, otherwise, the yield increase effect is not obvious.
2, pay attention to the right amount of medication: polycarbazole is a plant growth retardant that can be absorbed by roots, stems and leaves. If the concentration is too large or too much, it will infiltrate into the soil, which will inhibit the growth of peanuts excessively, which will not only increase the yield, but also produce a single-fruit phenomenon, which will reduce the yield; if the dosage is too light, the yield increase effect is not obvious. The suitable dosage is 15% to 400 times that of 15% paclobutrazol. At the same time, depending on the flower growth potential, the dosage should be increased or decreased as appropriate, and the growth is weak and the fertilizer and water deficiency are not suitable for application.
3, pay attention to the field water holding capacity: before and after spraying should pay attention to keep the soil moist in the field, too dry, unfavorable nutrient absorption, and will increase the inhibitory effect of paclobutrazol on peanuts, resulting in a single kernel phenomenon.
Peanut use Paclobutrazol III
Paclobutrazol is a systemic and versatile plant growth retardant that can be absorbed by the roots, stems and leaves of crops and acts on the entire plant. The proper use of paclobutrazol in peanut cultivation can effectively inhibit the growth of apical buds, control the growth of the shoots, make the plants dwarf, enhance the lodging resistance and photosynthesis, increase the fruit set rate, improve the quality, increase the fullness, and achieve high yield and quality. However, if it is used excessively or improperly used, it will not increase the production effect, or even counteract the effect, resulting in a single-fruit phenomenon, which leads to reduced production and reduced income. Therefore, use it with caution during use.
