Increase production

Roots and leaves of vegetables in the seedling stage or prolonged period, spraying 200~300ppm of paclobutrazol 50kg per acre can promote vegetable leaf thickening, internode shortening, plant stout, improve quality and increase yield. For example, before the picking, the cucumber is sprayed with 400 mg/liter of paclobutrazol, and the yield is increased by 20%~25%.

The four-leaf stage of autumn cucumber in greenhouse is sprayed with 100 mg/L of paclobutrazol solution. The internodes are shortened, the plant shape is compact, the stems are thickened, the resistance to powdery mildew and downy mildew is enhanced, the cold resistance is increased, and the fruit setting rate is increased. The yield increase is about 20%.

In the 3~4 leaf stage, the cabbage is sprayed with 50~100 mg/l paclobutrazol solution, which can dwarf the plant and increase the seed collection by 10%~20%.

When radish is sprayed with 45 mg/L of paclobutrazol in 3~4 true leaves, it can enhance the resistance and reduce the incidence rate. In the period of fleshy root formation, spraying with 100 mg/L of paclobutrazol can inhibit the growth of the plant. Inhibition of bolting, the leaves of the plants are green, the leaves are short and stａnd upright, enhance photosynthesis, promote the transport of photosynthetic products to the fleshy roots, increase yield by 1~20%, prevent the heart and improve the commerciality.

When the edamame is sprayed with 100~200 mg/L of paclobutrazol from the initial flowering to the full bloom period, the effective branching, effective pod number and pod weight can be increased, and the yield is increased by about 20%. When the vine climbs to the top of the rack, it is sprayed with 200 mg/L of paclobutrazol. If it grows too much, it can be sprayed once every 5~7 days, even if it is sprayed 2~3 times, it can inhibit stem and leaf growth and promote germination of side branches. Flower buds develop, tuber enlargement, increase yield by about 10%.

Promote early results

The application of nitrogen fertilizer in vegetable fields is excessive, or the shade of vegetables is insufficient, or the humidity of vegetables in protected areas is high at night, which often causes the stems and leaves of vegetables to grow long, affecting reproductive growth and fruit setting. 50 kg of 200 ppm liquid can be sprayed to prevent Stems and leaves are long, promote reproductive growth and have early results. During the formation of fleshy roots, foliar application of 100~150 mg/L of paclobutrazol, 30~40 liters per acre, can control the growth of aboveground parts and promote the hypertrophy of fleshy roots. Note that the concentration of the drug should be accurate and the spray should be uniform. Promote fruit ripening. After the fruit is finished, spraying with 500 mg / liter of paclobutrazol can inhibit vegetative growth and promote fruit ripening.

Precautions

Strictly control the amount of medication and the duration of medication. If the whole plant is sprayed, in order to increase the adhesion of the liquid, an appropriate amount of neutral detergent can be added to the liquid. If the dosage is too large and the concentration is high, causing the crop growth to be inhibited, the quick-acting fertilizer may be added, or the gibberellin may be used for the relief, 0.5-1 g per mu, and 30-40 kg of water.
