What kind of fertilizer is good for pear tree base fertilizer (base fertilizer application method)

The role of base fertilizer for pear trees

1. Because the base fertilizer for pear trees is mainly organic fertilizers such as human and animal manure, compost, green manure, and cake fertilizer, in order to facilitate the decomposition and utilization of these organic matter, it needs to be applied deeply. Deep application will inevitably cause many roots to be injured. This is the peak period of root growth, which will not only allow the injured roots to heal as soon as possible, but also promote the growth of a large number of absorbing roots, which is more conducive to the development of the root system and promotes absorption.

2. Since the production of new roots of pear trees can enhance the tree's nutrient absorption, it can promote the photosynthesis of autumn leaves, increase the tree's nutrient storage, promote the fullness of buds, and improve the tree's resistance to cold, all of which have a significant effect.

3. Because the autumn roots of the pear tree are well developed, the root system can become active earlier in the following spring and absorb nutrients earlier, which promotes flowering and fruiting of the aboveground parts. Also, because the organic fertilizer takes a long time to decompose, it can meet the nutritional requirements of the pear tree in spring.

Selection of base fertilizer for pear trees

Pear trees mainly use organic fertilizer as base fertilizer. You can use fully decomposed cow, pig, sheep, chicken manure, urban garbage, green manure, straw, weeds, etc., and add appropriate amounts of chemical fertilizers. It is generally best to apply fertilizer from September to October after harvesting the fruit.

How to apply base fertilizer to pear trees

It is best to apply base fertilizer to pear trees in autumn, as the effect is better than in winter and spring. Autumn is the second growth peak of the plant and the peak of continuous differentiation of flower buds and leaf buds, so the demand for fertilizer is greater. At that time, the soil temperature is still high and the soil moisture is also high. The fertilizer will decompose quickly and can be easily absorbed and utilized by the roots, which is beneficial to the growth and flowering in the coming year.

When applying base fertilizer to pear trees, you need to prepare the land first, make a ditch 50 cm deep and 40 cm wide, mash the fertilizer and mix it evenly with the soil, and water it thoroughly after application so that the fertilizer can take effect in time.

How much base fertilizer should be applied to pear trees?

The base fertilizer for pear trees is mainly human feces or poultry manure. After sufficient decomposition and fermentation, the organic fertilizer produced can be used about 150 kilograms, and it can also be combined with some chemical fertilizers.

How to apply fertilizer to pear trees

The topdressing for pear trees is mainly quick-acting fertilizer, which should be applied 3 to 4 times a year.

1. Top dressing before flowering: The tree is sensitive to nitrogen fertilizer during this period, so top dressing should be applied in time to increase the fruit setting rate. However, there is no need to apply top dressing to young and vigorous trees at this time.

2. Topdressing after flowering: After the pear tree blooms, timely topdressing can promote the growth of new shoots and reduce physiological fruit drop. During this period, nitrogen fertilizer is still the main type of topdressing.

3. Top dressing during the fruit enlargement and flower bud differentiation period: Top dressing during this period is beneficial to fruit enlargement and flower bud differentiation, and nitrogen, phosphorus and potassium should be appropriately combined.

4. Top dressing in the late stage of fruit development: Top dressing at this time can increase single fruit weight and fruit quality, and is also beneficial to flower bud differentiation. Top dressing in the late stage is particularly important for late-maturing varieties, and should be mainly composed of phosphorus and potassium fertilizers.
