How to fertilize a mulberry tree? A detailed explanation of fertilization methods
Mulberry is a fruit that many friends quite like; it tastes delicious, and many people grow mulberry trees themselves, so they can not only eat tasty mulberries but also green the air. However, growing mulberry trees is not that easy, especially fertilization, as fertilization differs in every season. Below, the editor brings you mulberry fertilization methods. Let's take a look.
1. Spring fertilizer for mulberry
Spring fertilizer is also called bud-promoting fertilizer. It is generally applied before the mulberry tree begins growing, mainly using quick-acting chemical fertilizers. The amount of spring fertilizer applied accounts for about 25%-30% of the whole year's fertilization. It is generally applied in two rounds. One round is in late March, applying 1000-1500 kg of manure and urine fertilizer per mu and about 2 kg of urea; the first application amount is about 70% of the total spring fertilizer. The second fertilization is in late April, applying about 10 kg of urea per mu is enough, to promote young bud growth.
2. Summer fertilizer for mulberry
The timing of summer fertilizer application is generally from summer pruning of the mulberry tree until before raising early-autumn silkworms. It is likewise applied in two rounds. One fertilization is carried out immediately after summer pruning; the fertilizer should preferably be organic fertilizers such as barnyard manure and compost applied together with chemical fertilizers. Generally, about 1000 kg of manure fertilizer per mu, 30 kg of urea and about 15 kg of phosphate fertilizer are applied. The second fertilization is carried out after bud thinning; at this time the fertilizer should mainly be quick-acting chemical fertilizers, applying 15 kg of urea per mu. The amount of summer fertilizer applied is generally 40%-50% of the whole year's fertilization.
3. Autumn fertilizer
The timing of autumn fertilizer application is generally after the autumn mulberry leaves are harvested. Autumn fertilizer should not be applied late, and at the latest must not exceed August; otherwise, branch and shoot growth is delayed and highly susceptible to freezing injury. Autumn fertilizer should mainly be quick-acting fertilizer. Under normal circumstances, about 15 kg of urea is applied per mu. The amount of autumn fertilizer applied is generally suitable at about 10%-20% of the whole year's fertilization.
4. Winter fertilizer
Winter fertilizer is applied before the soil freezes in winter. The amount of winter fertilizer applied generally accounts for about 20% of the whole year's fertilization. Organic fertilizers should preferably be chosen, such as barnyard manure, compost, river and pond mud, etc. It can be plowed in together with winter plowing to help the plant overwinter.
