Fruits and vegetables can provide the human body with vitamins, dietary fiber, fructose, and rich carbohydrates, balanced nutrition, enhance human immunity, and improve the quality of life! How can you eat big, sweet, and delicious fruits? Today, follow the editor to understand what fertilizer is good for fruit expansion fertilizer?
What fertilizer is good for fruit expansion fertilizer - autumn moon pear effect
1. The growth cycle of fruit trees, taking Qiuyue pear as an example.
The whole growth cycle of fruit trees can be divided into postharvest confinement fertilizer, autumn fertilization before defoliation, root germination period when ground temperature rises, flowering and fruit setting stage, young fruit expansion stage, hard core stage, second fruit expansion stage, sweetening and veraison stage, and maturity stage.
Autumn pear blossom is good or not, fruit setting rate is good, fruit setting quality is closely related to the confinement fertilizer and autumn fertilization after the autumn pear picking, the general fertilization principle of confinement fertilizer maintenance roots, promote the accumulation of tree nutrients, promote flower bud differentiation, can be used with rooting agent, balance microbial agent, balance granular fertilizer and balance powder A large number of elements can be used. At the same time, it can be appropriately combined with high phosphorus powder, macro-element water-soluble fertilizer or foliar spray of amino acid foliar fertilizer and potassium dihydrogen phosphate to promote branch lignification and flower bud differentiation.
Autumn fertilization must be the application of granular microbial agent and balanced granular fertilizer with medium and trace elements before the root system enters the dormant period and leaves fall, so as to further accumulate nutrients and enhance tree strength and stress resistance. In the second year, the autumn moon pear bloomed in large amount, the pear flower shape was large, the pistil stigma was fully developed, the anther pollen activity of the stamen was high, the fruit setting rate was high, and the fruit setting quality was good, which was the first step to achieve the high quality and yield of autumn pear.

The focus of the management of Qiuyue pear from entering the young fruit expansion period is fruit development, how to seize the fruit expansion period to make Qiuyue pear expand rapidly? We need to understand the commercial fruit standard of Qiuyue pear: 90-95 fruit, no mechanical damage on the fruit surface, no fruit rust, rust spots, sugar content of 13 sugars and above, low residue rate, juicy and slightly sweet.
2. The constraints affecting the development and expansion of Qiuyue pear fruit and what fertilizer is good for fruit expansion?
1. Root system and soil are the first factors restricting the expansion of Qiuyue pear fruit!
The root system is the "mouth" of the fruit tree, the root system is not good to affect the absorption of nutrients, the lack of nutrients causes the fruit to expand slowly, or the lack of nutrients causes the phenomenon of fruit shrinkage, especially the trace elements affect the activity of enzymes, resulting in the decline of photosynthesis efficiency, the accumulation of photosynthetic products is less resulting in no fruit, and the direct factor affecting the health of the root system is the soil, the heavy metals in the soil and water exceed the standard and soil acidification, salinity will lead to the growth and development of fruit tree roots, soil acidification causes the serious occurrence of fruit tree root-knot nematode disease, weakening the tree potential, Soil salinity, the increase of solution concentration causes root water loss, and improper fertilization causes the increase of soil solution concentration and fertilizer damage. At the same time, soil salinity and acidification will lead to the reduction of the availability of trace elements in the soil, which is more likely to cause nutrient deficiency in fruit trees, which directly affects fruit expansion.

It is recommended that fruit farmers can use a large number of elements and granular microbial agents, and if the problem is serious, you can choose to use rooting agents, mineral potassium fulvic acid, microbial agents and other products. By degrading complex soil and heavy metals in water, softening water quality allows nutrients to be better supplied to aboveground plants, and at the same time, soil health is repaired through bacterial supplementation and organic matter supplementation, and soil self-regulation and repair ability is improved, and soil is fertilized.
2. Timely topping, control the prosperity, so that the nutrients can be refluxed to supply the fruit to expand and develop.
The focus of management in the fruit expansion period is to promote fruit expansion, and excessive growth of branches and leaves will consume a large amount of nutrients, which will reduce the supply of nutrients to the fruit, and excessive vegetative growth inhibits reproductive growth, resulting in unsatisfactory fruit expansion. What fertilizer is good for fruit enlargement fertilizer? It is suggested that fruit farmers can use paclobutrazol combined with potassium dihydrogen phosphate for growth control, or use amino acid foliar fertilizer combined with potassium dihydrogen phosphate high-concentration foliar spray for effective growth control, so as to promote the return of nutrients to the fruit and promote fruit expansion.
3. During the fruit expansion period, sufficient nitrogen fertilizer should be applied to strengthen calcium supplementation, improve the degree of fruit expansion, and increase the commodity rate!
The nutrient element of fruit swelling is nitrogen, nitrogen mainly promotes the growth and development of fruit peel, insufficient nitrogen fertilizer application before the fruit hard core stage, excessive use of phosphorus and potassium fertilizer is often the main factor causing fruit swelling, phosphorus promotes differentiation, root tip growth, promotes flower bud differentiation, potassium promotes fruit sugar and color change, and potassium can enhance leaf photosynthesis to make carbohydrates to better transport to fruit. What fertilizer is good for fruit enlargement fertilizer? It is recommended that fruit farmers use high-nitrogen fluid fertilizer, high-nitrogen powder with a large number of elements, with balanced granular fertilizer, and calcium supplementation at the root.
Today's sharing of what fertilizer is good for fruit expansion fertilizer is over here, I hope you can have better benefits!
