Wheat has a good time to apply regulators

    Spraying the conditioner on the wheat at a suitable time can increase the yield and quality. Below, Xiaobian introduces the regulators that should be sprayed at various stages of wheat as follows:

    First, paclobutrazol.

    During the jointing period of wheat, the average spraying of 200ppm paclobutrazol solution per mu is about 50 kg, which can make the plant dwarf, enhance the lodging resistance and drought resistance. And it can treat powdery mildew and increase the absorption and utilization of nitrogen by crops.

    Second, squat.

    Groups of relatively large, strong growth momentum wheat, wheat jointing stage, the average per acre CCC agent formulated five percent of 40ppm to 50ppm liquid spray 40 kg to 50 kg, the control internode elongation, It can control the vegetative growth of wheat, promote reproductive growth, and make the plant body thick, thicken the leaves, and enhance the lodging resistance of the plants. If used in combination with 2 , 4 - D , it can also treat broadleaf weeds in wheat fields.

    Third, the growth factor.

    During the jointing period of wheat, the average use of 15 ml to 20 ml per acre , adding 50 kg of foliar spray of clear water , can control the inter-segment elongation, avoiding the late lodging and increasing the yield by 20%.

    Fourth, ethephon.

    From the booting of wheat to the filling stage, using 50ppm to 300ppm of ethephon 50kg sprayed leaves can increase the seed setting rate and promote grain fullness.

    Five, gibberellin.

    Wheat jointing period, the average per acre spraying a solution of about 500ppm of GA 40 kg, it is possible to reduce the invalid leaf, spike rate increase, 40ppm gibberellin spraying liquid per acre in 40 kg wheat booting time may increase spike The number of grains increases the weight of thousands of grains.

    6. Naphthaleneacetic acid.

    Before the wheat jointing, spray 25ppm naphthaleneacetic acid once, and then spray 20ppm naphthalene acetic acid one week after the flowering, and increase the seed setting rate, and promote the grain fullness, which can increase the yield by 15% per mu.
