How to fertilize figs? Fertilization timing and methods explained clearly at once
The fig is a flowering plant with a beautiful tree shape and good ornamental value; its fruit can not only be eaten fresh, but also processed into various side products such as juice, jam, and dried fruit, giving it high edible value; finally, figs can also be used as medicine, giving them certain medicinal value. In recent years, figs have been planted in all regions of our country, so after figs are planted, how should we fertilize them? Let us learn about it together below.
1. Base fertilizer
The base fertilizer for figs is mainly organic fertilizer, used in combination with an appropriate amount of chemical fertilizer. The chemical fertilizer is generally a nitrogen-phosphorus-potassium ternary compound fertilizer. This can provide nutrients to the fig plant for a relatively long time, maintain normal tree vigor, improve the immunity of the fig tree, and thereby promote high yield and high quality of figs. The base fertilizer for figs is generally applied between November and December, but the best fertilization time is from the end of February to early March. When fertilizing, the main method is trenching, with a trench depth of about 35 to 45 cm, and the base fertilizer amount per mu is generally controlled at about 600 jin.
2. Topdressing
The later topdressing of figs generally needs to be carried out in multiple applications, mainly based on the fertility level of the soil and the growth condition of the figs. If the soil fertility is insufficient, generally 7 to 8 topdressings are needed, but under normal circumstances, generally 3 to 4 topdressings are needed. During the growth period of the fig tree, if the leaves turn yellow and the tree body is thin and weak, then it is relatively nutrient-deficient. At this time, nitrogen fertilizer is mainly used for topdressing, with an amount of about 600 jin. When the fig enters the flowering and fruiting period, we mainly use potassium fertilizer to promote the enlargement of the fruit, with an amount of about 400 jin. In addition, during the ripening period of figs, we need to appropriately apply compound fertilizer, with an amount of about 200 jin. Finally, in order to avoid the phenomenon of fruit cracking in figs, it is also necessary to appropriately spray potassium fertilizer.
3. Fertilizer requirement
Figs generally should best not be continuously cropped, but their fertilizer requirement is relatively large, so multiple topdressings are needed during their growth process. In the normal planting process, the amount of base fertilizer applied generally accounts for about 25 percent of the total annual fertilization amount. For the later topdressing amounts, the first topdressing amount is controlled at 25 percent of the total fertilization amount, the second topdressing amount is controlled at 30 percent, the third topdressing is controlled at 15 percent, and the last topdressing is controlled at about 5 percent. Too much or too little fertilizer application will affect the growth of figs, so fertilization must be scientific.
The above is what the editor wants to share with everyone today, an introduction to the fertilization methods for figs. I hope it can help everyone.
