At what stage does peanut control flourish play?

Peanuts need to control prosperity in the process of growth, otherwise it is easy to grow in vain, so at what stage do peanuts control prosperity? Let's have a look!

First, why should peanuts control prosperity?

1. Prevent plant lodging

Peanuts in the case of sufficient water and fertilizer, high temperature and good light, the growth rate is accelerated, which is very easy to cause stems and leaves to grow. If it is not controlled in time, the height of peanut plants will be easy to lodge.

2. Prevent pods from being plump and yield reduced.

If the nutrition of peanut is absorbed by stems and leaves, the nutrition absorbed by pods will become less, and the fruit will not be full. At the same time, it will also lead to premature senescence in the later stage of peanut fruit, which will affect the yield and quality of peanut.

Second, at what stage does peanut control flourish?

The control of peanut growth can be done at the full flowering stage, early flowering stage, late needling stage to early podding stage of peanut, or when the height of the main stem is 35-40cm. Among them, 15% paclobutrazol per mu was sprayed with 50 g paclobutrazol and 30 jin of water at full flowering stage, plants were sprayed with 50-100mg per liter uniconazole solution at early flowering stage, and plants were sprayed with 200-500mg per liter at full flowering stage to podding stage, and good growth control effect was obtained when used continuously for 2-3 times.

What are the varieties of peanuts?

1. Dragon type

Plants prostrate and alternately flowering, pods with keels (dorsal ridge) and hooks, hockey-shaped. The reticulation of the fruit shell is deep, and the fruit needle is fragile and easy to break.

2. Multi-grain type

Inflorescences can be borne in each node of lateral branches, rarely twice branched, there are inflorescences in the main stem, there are obvious anthocyanins on the stem branches, 3-4 seed pods account for the majority, and the seeds are cylindrical.

3. Ordinary type

Inflorescences alternate on lateral branches, the leaf blade is Obovate, and the plants are erect, tufted and even creeping. The fruit is larger in shape. Seeds long cylindrical. The growth period is longer.

4. Pearl bean type

The lateral branches are close to the main stem and can produce several inflorescence nodes continuously, with only a few twice branched. Leaf blade elliptic, light green or green. Plants erect or tufted. The fruit shape is smaller. The seeds are peach shaped. Weak dormancy.
