Which kind of foliar fertilizer is good for the latest peanut high yield?

Foliar fertilizer is a type of fertilizer that nutrients are applied to the surface of crop leaves and play their role through the absorption of leaves. As a supplement for plant absorption of nutrients, it is worth noting that foliar fertilizer cannot replace soil fertilization. Let's take a look at which kind of peanut high-yield foliar fertilizer is good!

Which kind of peanut high yield foliar fertilizer is good?

Peanut foliar fertilizer has the effect of high fertilizer absorption and utilization rate, saving fertilizer and increasing yield significantly. Nitrogen, phosphorus, potassium and other macroelements and calcium, molybdenum, boron, manganese and iron can be applied to foliar fertilizer. Foliar N fertilizer increased the number of full fruits obviously, foliar P fertilizer increased the yield by 7~10%, foliar Al, B, Mn, Fe fertilizer increased the yield by 8~10%. Peanut in the selection of foliar fertilizer is best to choose the brand registered in the Ministry of Agriculture, and the selection of special foliar fertilizer is better.

Principles of fertilizer requirements for peanuts

1, a large number of elements: peanut nitrogen phosphorus and potassium ratio requirements for 3: 0.4: 1, nitrogen is the most, followed by potassium, phosphorus is the least, for this reason in a large number of element fertilizer topdressing should be mainly nitrogen, potassium appropriate.

2, trace elements: peanuts on calcium, sulfur, magnesium and other elements demand the most, calcium can promote peanut plants to accelerate growth, sulfur can improve the protein content of nuts, magnesium can promote the normal formation of peanut chlorophyll.

How to use peanut foliar fertilizer

1. Fertilizer dilution: Take 35 grams of concentrated liquid fertilizer and add 20 kilograms of clear water, dissolve and stir evenly, preferably tap water, pond water and rainwater have more impurities.

2, foliar spraying: peanut foliar fertilizer spraying to the back of peanut leaves, uniform spraying, sprayer can choose a good atomization effect, conducive to foliar absorption.

3. Spraying time: The best time for spraying foliar fertilizer on peanuts can be at the beginning of fruiting period after flowering, spraying once every 10 days or so, which can increase the yield of expanded fruits.

Peanut foliar fertilizer precautions

1, according to peanut growth and growth period to determine the fertilization time, generally should be applied in the late growth period.

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

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

4. When spraying peanut foliar fertilizer, spray evenly and spray fine, and spray both sides of the leaves.
