How many days is the growing period of summer peanuts? When is the latest time to sow summer peanuts?

The growth cycle of summer-sown peanuts is about 150 days . When planting, you can choose humus soil with high trace element content and loose soil as the base soil. It can be used as the base soil before planting. It can also be air-dried before planting to improve soil permeability, and base fertilizer can also be added to the soil.

How many days does it take for summer-sown peanuts to mature?

Growing period: The growth cycle of summer-sown peanuts is about 105 to 115 days . The growth period is short and the yield is generally low. Attention should be paid to its cultivation and management techniques to increase the yield and income of summer-sown peanuts.

Planting time: The planting time of summer peanuts is generally around June every year . Peanuts are suitable for planting under warmer climate conditions, which is beneficial to rooting and germination. The climate will gradually rise in the later period, and the latest sowing time should not exceed June 20 .

Summer peanut planting method

1. Variety selection

According to the growth characteristics of summer-sown peanuts, the temperature is low in the later stage of peanuts, which is not conducive to the growth of the fruiting period. Therefore, in order to obtain high yields, good varieties must be selected. It is recommended to use high-quality varieties such as Huayu No. 22, Huayu No. 17, and Luhua No. 11 .

2. Select the plot

Summer peanut planting has a short growth period and concentrated fertilizer absorption time, so it is necessary to choose fertile, loose soil, and loam or river silt plots with good drainage and irrigation conditions. At the same time, according to the peanut fertilizer absorption law, combined with stubble removal and ridge formation, fertilizer should be applied at one time.

3. Early sowing

The main factor limiting the high yield of summer peanuts is the short growing period. Early sowing is of key significance. We should strive to sow before June 15 and no later than June 20 .

4. Sowing method

The "dry sowing and wet output" method can be adopted. For example, peanuts can be planted in ridges and irrigated along the ridges after sowing. For peanuts covered with film, drip irrigation under the film should be used, and for peanuts in the open field, micro-spraying and other methods can be used.

Summer peanuts planted in ridges and covered with film should be sown shallowly and covered with soil. The sowing depth should be controlled at 2-3 cm. After sowing, cover the film and suppress it. Cover the film with 4-5 cm of soil to ensure that the hypocotyls are elongated and the cotyledon nodes are unearthed (film).

5. Intertillage and weeding

Do not carry out inter-row cultivation and weeding after film covering. Before film covering, you can use 200 grams of clarithromycin mixed with 75 liters of water and spray it after dilution, or use 100 grams of sethoxydim to spray 45 liters of water, but you must pay attention to the method and dosage.

6. Pest and disease control

In order to prevent summer-sown peanuts from diseases and pests and premature aging in the later stage, agricultural pesticides such as mancozeb, carbendazim, and chlorothalonil can be used for prevention and control. Generally, spraying begins in early August, once every 10 days, and continues for 2-3 times.

7. Foliar spraying

In the late growth stage of peanuts, use 0.5 kg of urea plus 0.2 kg of potassium dihydrogen phosphate and 50 kg of water per mu and spray the leaves 2-3 times to prevent premature aging, which is critical to increasing peanut yield.
