How to select peanut seeds? What are the breeding methods?

Peanut is one of the most important oil crops in China, and its planting area is very wide. of course, in addition to oil crops, peanuts have a very good prospect in the processing market. So how to choose peanuts? What are the methods of raising seedlings?

First, how to select peanuts?

1. Dihao No. 6

Normal type. Edible, fresh food, oil use. The growth period of small grain variety is 123.8 days, the plant type is erect, the height of main stem is 39.5cm, the length of lateral branch is 43.9cm, the total branch is 8.4cm, and the fruit branch is 7.7cm. The leaves are long oval and dark green.

two。 Pukehua No. 3

Edible, fresh, oil, oil and food both. The common peanut variety with sparse branches and erect early maturity has a growth period of 116 days in summer.

3. Qihua No. 1

General type, edible, fresh, oil, oil and food both. The growth period of spring sowing is about 130 days, the pod is ordinary and medium size, the seed kernel is oval, the seed coat is pink, the color is light, the inner seed coat is white, and the pod kernel is neat in size.

4. Fuhua 27

Pearl bean type. Edible, fresh food. For continuous flowering erect small peanut, the average growth period is 124 days, the height of the main stem is 37.6 cm, the plant type is compact, the plant line is developed, and the results are concentrated.

Second, what are the methods of raising peanuts?

1. Seed drying before sowing

After a long period of storage, peanut seeds are easy to absorb water in the air and increase the water content of the seeds, so it is necessary to sun the seeds for 2-3 days before shelling. When drying seeds, you should pay special attention not to put them on the cement yard and slate, lest the temperature is too high and damage the germination ability of the seeds.

two。 Shelling and particle separation

The main results are as follows: (1) the shelling time is as close to the sowing time as possible.

(2) method of particle separation

① was shelled by hand and graded according to grain weight.

② screening classification, seed selection sieve for rectangular wooden frame, the bottom nailed on the No. 8 aluminum wire or bamboo, sieve hole rectangular, the gap is generally 5mm, 7mm two, first sieve with a 7mm sieve hole, select secondary seeds, sifted down for the tertiary seeds (generally not used as seeds), leaving primary and secondary seeds as seeds, while picking out fragments, susceptible seeds and seeds with mildew characteristics.

3. Germination test

Before shelling, the representative seeds were taken, mixed evenly and then germinated. 50 or 100 seeds were used in each sample and repeated for 3 or 4 times. The germination potential of peanuts for seed use should be more than 80%, and the germination rate should be more than 95%. Before it can be used for sowing.

4. Soaking seeds to accelerate germination

The whole seedling, quick emergence and alignment can be realized. There are two methods to soak the seeds to accelerate germination, one is to soak the seeds in warm water of 30 ℃ and 40 ℃, and then to remove them and put them into the environment of 25 ℃ to accelerate germination, and the other is to discharge the dry seeds in layers with wet sand at the ratio of 1:5 to make them germinate by absorbing water. The two methods should pay attention to heat preservation, moisturizing and proper ventilation. After most of the seeds germinate, those who have already germinated are picked out and sown.

5. Coating

Coat with 0.3% seed amount of Seelot suspension seed coating.

6. Seed dressing

There are two kinds of fertilizer seed dressing: fertilizer seed dressing and chemical seed dressing. Seed dressing with 1kg of biological phosphorus and potassium fertilizer per 667 square meters can be seen in the part of pest control.

If you also want to plant peanuts in a large area, please be sure to choose the species well, and it is better to choose them according to the local climate and environment.
