What fertilizer is suitable for peanuts? Detailed explanation of topdressing time and methods
Peanut is a common plant in daily life. It can be used for oil pressing, application, making lubricants, and so on, and it has relatively high economic value. It is cultivated in most areas of our country.So what fertilizer is suitable for planting peanuts? Are you clear about the topdressing time and methods?Next, the editor of Tuliu.com will introduce them to you one by one.
I. Basic information about peanuts
1. Origin of peanuts
Peanut generally refers to the groundnut, an annual herbaceous plant, also called earth bean, longevity fruit, potato (Taiwan dialect), Tangren bean or Nanjing bean (Japan), and is distributed in Brazil, China, Egypt, and other places. In our country, it is mainly distributed in Liaoning, Shandong, Hebei, Henan, Jiangsu, Fujian, Guangdong, Guangxi, Sichuan, Jilin, and other provinces (regions). Among them, Shandong Province has the largest planting area and the highest yield.
2. Price of peanuts
In Queshan, Zhumadian, Henan, the reference purchase price of wheat-stubble white sand common peanut kernels is about 3.65 yuan/jin, and a few good sieved goods are priced at 3.70 yuan/jin; good refined kernels on the 7 sieve are referenced at 3.95 yuan/jin for loading, and refined kernels on the 8 sieve are referenced at 4.10-4.15 yuan/jin for loading; in Laixi City, Shandong, good common kernels of Huayu 22 and Huayu 31 are purchased at about 4.3 yuan/jin; traditional double-kernel fruits are purchased at about 4.5 yuan/jin, with moisture around 8, and seed fruits of Huayu 22 and Huayu 31 are about 4.4 yuan/jin; in Zhengyang, Henan, the price of new white sand common kernels is 3.65-3.70 yuan/jin, selected kernels on the 7 sieve are about 4.20 yuan/jin, and the price of selected kernels on the 7 sieve is about 4.20 yuan/jin.
3. Peanut yield per mu
Generally, the peanut yield per mu varies by variety and region. Its growth period is 100-150 days, and some late-maturing peanut varieties have a growth period of about 180 days. Usually, the peanut yield per mu planted on fertile soil is about 1000 jin, while on poorer land the yield per mu is 600-800 jin.
II. What fertilizer is suitable for planting peanuts?
Plant cultivation cannot be separated from fertilizer. Especially if you want to obtain high-yield and high-quality peanuts, fertilizer is even more important. The fertilizers suitable for planting are organic fertilizer, phosphorus and potassium fertilizer, and mixed farmyard manure of human feces and plant ash. Note that different fertilizers should be applied at different growth stages of peanuts.
III. The topdressing time and methods for planting peanuts must be clear!
Timely topdressing of peanuts can promote early seedling development and improve the quality and yield of peanuts, so when to fertilize and what fertilizer to topdress are very important.
1. Topdressing time for peanuts
(1) At the peanut seedling stage (3-5 leaves of growth), apply quick-acting nitrogen fertilizer and Flower Promotion King No. 3 to promote more flowering and branching in peanuts, which can increase the number of flowers and pods.
(2) Just after peanuts begin to flower, topdress with nitrogen fertilizer, and at flowering apply compound fertilizer and calcium fertilizer.
(3) During the peanut pod-filling stage, apply phosphorus fertilizer, spraying potassium dihydrogen phosphate plus Xin Gaozhi film once every 7-10 days, continuously spraying two or three times.
(4) At the peanut cluster stage, topdress 7-10 kg of compound fertilizer per mu, together with 5 kg of urea as topdressing.
2. Topdressing methods for peanuts
(1) If the base fertilizer used for peanut planting is insufficient and the soil fertility is not enough, timely topdress seedling fertilizer, applying 8-10 jin of nitrogen fertilizer per mu, or 30-40 jin of compound fertilizer; you can choose broadcasting or furrow strip application.
(2) At the flowering and pegging stage, topdress 40 jin of superphosphate per mu + 500 jin of high-quality organic fertilizer per mu, but the application amount of nitrogen fertilizer should be controlled well.
(3) In the later growth stage of peanuts, when the root system ages, spray foliar fertilizer, generally once every seven days, and about three consecutive sprays are enough.
(4) When topdressing peanuts, be sure to note that before and after flowering, if drought weather occurs, do not flood irrigate.
The above is all the content about fertilization for peanut planting. When fertilizing, everyone must act according to the soil fertility, and the fertilization amount and time must also be controlled well.
