How to Fertilize Figs: A Detailed Guide to the Latest Fertilization Methods
The fig is a flowering plant with a graceful tree shape and good ornamental value; its fruit can not only be eaten fresh but also processed into various secondary food products such as juice, jam and preserved fruit, giving it high edible value; finally, figs can also be used as medicine and have 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 the fig plants with nutrients 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 digging trenches, 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 according to 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 3 to 4 topdressings are generally needed. During the growth period of the fig tree, if yellowing and weak tree growth occur, then the nutrition is relatively insufficient; at this time, nitrogen fertilizer is mainly applied as topdressing, with an amount of about 600 jin. When the fig reaches the flowering and fruiting stage, we mainly use potassium fertilizer to promote the swelling of the fruit, with an amount of about 400 jin. In addition, during the ripening stage of figs, we need to properly apply compound fertilizer as topdressing, with an amount of about 200 jin. Finally, in order to avoid the phenomenon of fruit cracking in figs, it is also necessary to properly spray potassium fertilizer.
3. Fertilizer requirement
It is generally best not to carry out continuous cropping of figs, 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 generally accounts for about 25 percent of the total annual fertilizer amount. For the later topdressing amounts, the first topdressing amount is controlled at 25 percent of the total fertilizer amount, the second topdressing amount at 30 percent, the third topdressing at 15 percent, and the last topdressing at about 5 percent. If the fertilizer amount is too large or too small, it will affect the growth of figs, so fertilization must be scientific.
