Which kind of high yield foliar fertilizer is good for peanuts?

Foliar fertilizer is a type of fertilizer in which nutrient elements are applied to the surface of crop leaves and play its function through the absorption of leaves. As a supplement to plant absorption of nutrients, foliar fertilizer can make up for the deficiency of root absorption of nutrients. It is worth noting that foliar fertilization can not replace soil fertilization. Let's take a look at which foliar fertilizer is good for high yield peanut.

Which kind of high yield foliar fertilizer is good for peanuts?

Foliar fertilizer of peanut has the effect of high fertilizer absorption and utilization, saving fertilizer and increasing yield. A large number of elements such as nitrogen, phosphorus, potassium and trace elements such as calcium, molybdenum, boron, manganese and iron can be applied on the leaf. Foliar application of nitrogen fertilizer significantly increased the number of full fruits, foliar application of phosphate fertilizer can generally increase the yield by 710%, foliar application of aluminum, boron, manganese, iron and other micro-fertilizers can generally increase the yield by 810%. When choosing foliar fertilizer, it is best to choose the brand registered in the Ministry of Agriculture, and it is better to choose special foliar fertilizer.

The principle of fertilizer demand for peanuts

1. A large number of elements: the proportion of nitrogen, phosphorus and potassium in peanuts is 0.4: 1, nitrogen is the most, potassium is the second, and phosphorus is the least. Therefore, the application of a large number of element fertilizers should be mainly nitrogen and appropriate amount of potassium.

2. Trace elements: peanuts have the most demand for calcium, sulfur, magnesium and other elements. Calcium can accelerate the growth of peanut plants, sulfur can increase the protein content of nuts, and magnesium can promote the normal formation of peanut chlorophyll.

Application method of foliar Fertilizer for Peanut

1, fertilizer dilution: take 35 grams of concentrated liquid fertilizer to add 20 kilograms of clear water, dissolve and stir evenly, preferably tap water, pond water and Rain Water more impurities.

2. Foliar spraying: peanut foliar fertilizer is mainly sprayed on the back of peanut leaves, evenly sprayed, and the sprayer can choose the one with good atomization effect, which is beneficial to foliar absorption.

3. Spraying time: the best time for peanut to spray foliar fertilizer is at the beginning of fruiting period after anthesis, with an interval of about 10 days, which can increase the yield of expanded fruit.

Matters needing attention of foliar Fertilizer for Peanut

The main results are as follows: 1. The fertilization time should be determined according to the growth situation and growth period of peanut, and it should be applied in the later growth stage.

2. Spray before 9: 00 a. M. and after 4: 00 p. M. on windless or sunny days to increase leaf absorption and prevent damage to leaves.

3. It is necessary to strictly control the spraying concentration, which is easy to damage the leaves and cause fertilizer damage.

4. When spraying peanut foliar fertilizer, it should be sprayed evenly and carefully, and both sides of the leaves should be sprayed.
