Fruit trees are the main choice for most growers and are easy to produce and have high returns. If fruit trees are to be planted in the north, it is necessary to select more adaptive varieties to ensure winterization. What are the farm fats used in fruit trees? What are the recommended fruit tree varieties suitable for cultivation in the north? Let's take a look down there
What are the types of farm fat used in fruit trees
(1) manure
Manure is a good source of fruit-based fertilizer, but human urine is more chlorinated ion salt, which has a negative impact on the quality of fruit and is not suitable for use as fruit-tree fertilizer. Manure, which is stored separately in urine, is therefore used for fruit-based manure, which is not suitable for use as fruit-tree fertilizer。
(2) dung
How can livestock excreta produce different amounts of heat during decomposition? Temperature? Cold fertilizer. Cow manure is cold manure, pig manure is hot manure, horse manure? The manure is thermal fertilizer, but it produces less heat than horse manure. So, in cold winter areas, horse dung can be laid on the surface and covered with thin ground, with some heating。
(3) poultry
Nitrogen in poultry manure is mainly in the form of urea acid and cannot be directly absorbed by fruit trees, harmful to the growth of root systems, and fresh poultry manure is easy to attract ground pests and should be sufficiently decomposed for application. Poultry manure produces more heat during decomposition and is thermal fertilizer。
(4) compost
Compost is manure made out of straw, grass, leaves, garbage, etc., which is mixed with humans' urine, livestock's urine, etc. Compost is used in a variety of materials, the nutrient content varies considerably, but the organic content is rich, the nitrogen phosphorus potassium ratio is appropriate and contains many trace elements and phosphorus is abundant and easily absorbed by fruit trees. The organic content of high-temperature composting is 24% ~ 42%? All nitrogen content 1. 1% ~ 2. 1%? All phosphorus content 0. 3% ~ 0. 8%? All potassium content 0. 5% ~ 2. 5%。
Fruit tree varieties suitable for the north
I. Apple
It is easy to plant apple trees, which are able to adapt to most climates, both north and south, with fruit due in late august-october and usually fresh apples at the end of the summer and early autumn。
Ii. Almond trees
The apricot tree, which is dry, resilient and has a lifetime of over 100 years, is very suitable for one of the fruit trees grown in the north。
Date
The date is a very good fruit, rich in vitamin c, which can be eaten not only freshly, but also as a date of honey, which is popular and well suited to the farming environment in the north。
Iv. Salmons
Not many people have heard of such fruit, and it is extremely drought-resistant, although most are planted in desert areas and can survive on most salinized land in the north。
V. Grapes
Grapes are not so demanding for the growing environment as they are adapted to the needs of the soil, but as far as possible are sandy soil, which is more water-protecting and capable of meeting the large amount of moisture required for grape growth and is one of the fruit trees that is suitable for cultivation in the north。
That's what fruit trees are used to. The fruit tree species suitable for cultivation in the north are recommended. All the presentations are expected to help you。
