What should I pay attention to when planting spring peanuts?

Peanut, as one of the main oil crops, is a favorite crop for many farmers at present, and its economic benefit is higher than that of wheat and corn.

The preliminary work is very important for the planting of spring peanuts. There are many intermediate steps from preparation to sowing, which require farmers to do every step well.

First, the choice of peanut varieties

1. According to the growth period, it can be divided into three types, namely, early-maturing peanut varieties, middle-maturing peanut varieties and late-maturing peanut varieties. The growth period is different. Early-maturing peanut varieties are generally around 120 days, middle-maturing peanut varieties are generally around 145 days, and late-maturing peanut varieties are generally around 160 days.

2. According to the size of peanut pods, there are two main types, one is large pods and the other is small pods. Peanuts with big pods, thick shells and big peanuts. On the contrary, peanuts with small pods have thin shells and small peanuts.

3. According to the botanical characteristics of peanuts, they can be divided into four kinds, namely, common peanuts, pearl peanuts, multi-grain peanuts and long-lived peanuts, and most of the common peanuts and peanut grains are oval or rectangular; Pearl peanuts, peanuts are generally round or peach-shaped; Many peanuts, usually with 3-4 peanuts inside; Longsheng peanuts usually have three more in their pods.

Second, the sowing date of spring peanuts

The sowing date of spring peanuts is strict, neither too early nor too late. Under normal circumstances, most spring peanut planting areas will be planted between the middle and late April and early May, while some places will plant spring peanuts according to the solar terms, that is, when Grain Rain and Grain Rain arrive (Grain Rain in 2020 will be in April 19, which is also within the above range). However, there are also special circumstances. The temperature in some parts of the south is relatively high, and the seeds will be planted in the middle and late March.

Third, the sowing density of spring peanuts

Sowing density is also related to the final yield. We often say that suitable planting density is conducive to increasing production and improving varieties. However, how much to sow per mu is a point that many peanut growers are very concerned about.

The above three points are the management opinions (variety selection, sowing date and sowing density) of spring peanuts before sowing, and each point is more important. I hope it can bring some help to farmers who are going to plant spring peanuts in 2020. Of course, this is only the work during the sowing period. To achieve high yield, follow-up management is equally important.
