Description

A kind of special formula fertilizer for alkaline hickory and method for fertilizing hickory

technical field

The invention belongs to the technical field of agriculture, and in particular relates to a pecan fertilizer, in particular to an alkaline pecan special formula fertilizer and a pecan fertilization method.

Background technique

Hickory, Carya cathayensis is a deciduous tree, belonging to the Juglandaceae Hickory genus, is a deciduous tree, commonly known as small walnut, small walnut. There are about 20 species, of which 4 species are native to China and 11 species are native to North America. They are distributed on the mountainsides and gentle slopes of the foothills. The growth soils include: oily yellow soil, black lime soil, calcareous Shale and other soils, these soils have strong water permeability, good water retention, deep and fertile, slightly alkaline to neutral. Its footprints are almost all over the world, mainly in America, Europe and many places in Asia. my country is mainly distributed in the Tianmu mountainous area at the junction of Zhejiang and Anhui at 29-30° and 18-120°, namely Lin'an, Chun'an, Anji, Tonglu in Zhejiang and Ningguo, Shexian, Jingde, Jixi and other counties and cities in Anhui. Lin'an, Zhejiang is the central production area. The cultivation and utilization of hickory nuts has a history of more than 500 years. Due to the high economic value and nutritional value of hickory nuts, the unique taste and flavor of hickory nuts has been recognized by consumers and has gradually become a popular high-end nut. , known as "the most beautiful fruit in the world".

Features of hickory: Hickory trees are generally 12 to 13 meters high, and the highest can reach about 30 meters. Monoecious dioecious. The seed tree bears fruit in 7-8 years at the earliest, 20-50 years is the full fruit period, and gradually ages after 50 years, and the age of the tree can reach about a hundred years.

Carya is suitable for growing in neutral and slightly alkaline soil, and there is an obvious correlation between the fruit quality and soil properties in the distribution area of pecan. Among them, the crude fat content was significantly positively correlated with soil available phosphorus content; the crude protein content was significantly correlated with soil organic matter, hydrolyzed N and available phosphorus; the potassium element content was significantly positively correlated with soil available potassium; the sodium element content was significantly correlated with soil The pH value was significantly negatively correlated; the calcium element content was extremely significantly negatively correlated with the soil pH value; the magnesium element content also had a strong negative correlation with the soil pH value.

Nutrient elements and functions necessary for pecan growth are:

1. Nitrogen

Nitrogen is the raw material for the synthesis of important macromolecules such as proteins, and is the basic element of genetic material, chlorophyll and other key organic molecules. Nitrogen is a component of enzymes and various microorganisms. All organisms need nitrogen to Sustain life. Nitrogen is an important factor to ensure the normal growth and development of hickory and increase production and income.

2. Phosphorus

Phosphorus is a component of nucleic acid and nucleotide, and is the main component of protoplasm and nucleus. Many phospholipid compounds and multi-enzyme molecules in crops contain phosphorus, which has an important impact on the metabolic process of crops. P is a raw material for the synthesis of membranes, nucleic acids, and nucleotide derivatives (ATP, NAD, NADP, FMN, FAD, CoA, etc.), and participates in sugar metabolism (photosynthesis, respiration, synthesis, decomposition, transformation, transportation, etc.), lipid metabolism ( CoA, ATP, etc.), rational application of phosphorus fertilizers can increase crop yields, improve product quality, and accelerate the emergence and growth of hickory nuts.

3. Potassium

Potassium is not a component of organic compounds in plants, and mainly exists in the plant cell fluid in the form of ions. It is an activator of various enzymes and plays an important role in the metabolic process. It can not only promote photosynthesis, but also promote nitrogen metabolism and improve the absorption and utilization of nitrogen by plants. Potassium regulates the osmotic pressure of cells, regulates plant growth and economic water use, and enhances the ability of plants to resist adverse factors (drought, cold, disease, salinity, lodging). Potassium can also improve the quality of agricultural products.

4. Medium and trace elements

Elements with a content of 0.1% to 0.5% in plants are called secondary elements, and the contents of calcium, magnesium, and sulfur in plants are 0.5%, 0.2%, and 0.1% respectively, so they are listed as secondary elements. Recent studies have found that silicon is the fourth essential element after N, P, and K, and it is also included in the scope of medium elements. Elements with a content between 2×10 ^-7 and 2×10 ^-4 mg/kg are called trace elements, and there are nine essential trace elements including calcium, magnesium, zinc, boron, manganese, molybdenum, copper, iron, and silicon. The growth and development of crops need to absorb various nutrients, but what determines the crop yield is the effective plant growth factor with the smallest relative content in the soil, and the yield will change accordingly within a certain limit with the increase or decrease of this factor. Because of this limiting factor, it is difficult to increase the yield of crops even if other nutrients continue to be added. In the past 20 years, the application of nitrogen, phosphorus and potassium fertilizers has increased sharply, but the nutrients of medium and trace elements taken away with crops have not been systematically replenished. Therefore, the crops and soils in areas lacking medium and trace elements are becoming more and more widespread, and the problems are becoming more and more serious. It's getting serious.

Especially calcium, magnesium, zinc, boron, etc. are very active in plants. When a certain trace element in the soil that provides plant nutrients is deficient, the plant will appear "deficiency pathology", which will reduce the crop yield and quality, and even fail to harvest in severe cases. In this case, the application of trace element fertilizers to pecans often There will be a very obvious effect of increasing income. Therefore, to fertilize pecans, the soil must be conditioned, the elements must be complete, the proportion must be coordinated, the fertilization must be timely, and the method must be appropriate, in order to achieve a balance between the nutrient supply of the soil and fertilizer and the nutrient demand of the crop to achieve high-quality and high-yield, and obtain high-quality and high-yield hills. Walnut.

Contents of the invention

The first object of the present invention is to provide a special formula fertilizer for alkaline pecans, which is an organic and inorganic ecological fertilizer, and is a "high-efficiency, safe, and environmentally friendly" fertilizer. It combines three types of fertilizers: biological fertilizer, organic fertilizer and inorganic fertilizer. Combined, the synergistic and synergistic effects of biological fertilizers, the slow and long-term effects of organic fertilizers, and the quick-acting and high-efficiency of inorganic fertilizers are combined with each other. It is beneficial to the high quality and high yield of hickory.

The technical solution adopted by the present invention to solve technical problems is:

A special formula fertilizer for alkaline pecans, which is composed of the following components in parts by weight: 3-10 parts by weight of biological fertilizer, 10-50 parts by weight of organic fertilizer, 5-15 parts by weight of enzyme preparation and 5-35 parts by weight of inorganic Fat;

The organic fertilizer is sugar residue and lignin with a mass ratio of 3:1. The organic fertilizer has the advantages of slow release and long-term, and can effectively improve soil structure, fertilize soil fertility, and improve crop quality;

The enzyme preparation is a metalloprotease and a polycarbase with a mass ratio of 2:1. The main function of metalloprotease is to increase the nutrient absorption of crops, increase the ability of disease resistance and anti-oxidation and anti-aging. It is especially effective for the physiological diseases caused by cropping diseases and deficiency diseases. Polycarbase absorbs and fixes carbon dioxide in the air through active substances, which increases the concentration of crop roots and carbon dioxide, thereby enhancing plant photosynthesis, while adjusting the carbon-nitrogen ratio in plants, and enhancing plant stress resistance. The present invention adopts the mixture of metalloprotease and polycarbonase with a mass ratio of 2:1 as the enzyme preparation, which can maximize the synergistic effect of the two, make it the best in disease resistance and stress resistance, and at the same time increase the fruiting rate of hickory nuts , to increase its production.

The special formula fertilizer for alkaline hickory provided by the present invention adopts the combination of organic fertilizer and inorganic fertilizer, combining quick-acting and long-acting; at the same time, nitrogen, phosphorus, potassium and medium and trace element fertilizers are uniformly mixed to form compound fertilizer. Nitrogen, phosphorus, potassium, and medium and trace element fertilizers are essential nutrients for the growth and development of hickory nuts. They play different roles in the development and growth of hickory nuts, which is conducive to the high quality and high yield of hickory nuts.

Preferably, the biological fertilizer is bacillus, and the biological fertilizer has synergistic and synergistic effects, and at the same time can resist diseases and reduce environmental pollution.

Preferably, the inorganic fertilizer is at least one of nitrogen, phosphorus, and potassium fertilizers, and the inorganic fertilizer can provide the macroelements of nitrogen, phosphorus, potassium, and medium and trace elements necessary for the growth of hickory.

Walnut plants are tall, with well-developed root system, high yield and long life, and require a relatively large amount of fertilizer. Coupled with the growth of roots, branches and leaves, flower bud differentiation, leaching loss and soil fixation, the pure elements that should be supplemented every year should be more than 2 times larger than this. In the past, walnuts were planted without fertilization. Obviously, soil supply alone cannot meet their growth and development needs. During the growth process, walnuts not only require a large amount of macronutrients and secondary elements, but also comprehensively require micronutrients. According to leaf analysis, the pure elements contained in normal leaves are: nitrogen 2.50-3.25%, phosphorus 0.12-0.30%, potassium 1.20-3.00%, calcium 1.20-2.50%, magnesium 0.30-1.00%, sulfur 170-400mg/kg, Manganese 35-65 mg/kg, boron 44-212 mg/kg, zinc 16-30 mg/kg, copper 4-20 mg/kg, barium 450-500 mg/kg. If one of them is missing or the supply is insufficient, physiological disorders will occur and deficiency syndrome will occur, which will affect normal growth and yield quality. If zinc is deficient, the leaves will be small, yellow, and curled. In severe cases, the leaves of the whole tree will be small and curled, and the tops of the branches will die. If manganese is deficient, the leaves will lose chlorosis, the veins will become light green, and scorched spots will appear on the mesophyll and leaf margins, and they will fall prematurely. In case of boron deficiency, the branches will wither downwards, small brown spots appear between the veins of the leaflets, the leaflets are easily deformed, and the young fruits are easy to fall off. Such as copper deficiency, which often occurs at the same time as manganese deficiency, mainly manifested as nucleolus atrophy, early yellowing and shedding of leaves, black dead spots on leaflet epidermis, and severe branch death. Moreover, the lack of a certain element can only be corrected by supplementing this element, and supplementing other elements, such as boron deficiency and copper application, copper deficiency and zinc application, not only does not help, but sometimes even causes antagonism and inhibits the absorption of other elements, thereby triggering Other deficiencies or obesity.

The present invention simultaneously provides a method for fertilizing hickory nuts, which has a high fertilizer utilization rate and can meet the nutritional requirements of hickory nuts at each growth stage. The application method specifically includes the following steps:

(1) Sprout topdressing: From March to April every year, at the early stage of leaf expansion or early flowering, the quick-acting nitrogen fertilizer is applied by the method of hole fertilization, and the amount of fertilizer applied is 1.5-2kg/plant for large trees and 0.7-1 kg/plant for small trees. After sprouting leaves, physiological activities become more and more vigorous, growth and development accelerates rapidly, respiratory intensity increases, metabolism is enhanced, cell division is obviously accelerated, and a large amount of nutrients and energy substances are needed to make physiological activities such as hair growth and leaf growth, flowering and fruiting smoothly. conduct. Therefore, quick-acting fertilizer should be topdressed in time at this time, and the content of nitrogen fertilizer should be increased appropriately.

(2) Topdressing after flowering: in the period of young fruit after flowering fades from May to June every year, formula fertilizer A mainly composed of nitrogen and potassium fertilizers is applied by pit fertilization method. 0.7~1.5 kg/plant; topdressing at the young fruit stage after flower withering will help supplement the large amount of nutrients consumed by flowering and meet the nutrients needed for young fruit growth, thereby reducing physiological fruit drop, improving fruit setting, and accelerating young fruit growth.

(3) Topdressing in the hard shell stage: From June to July every year, apply formula fertilizer B with the method of hole fertilization, and the amount of fertilizer applied is 2-2.5kg/plant for large trees and 1-1.2kg/plant for small trees. During the hickory hard shell period, the hardening of the pericarp, the development of the nucleolus and the differentiation of flower buds all require a large amount of phosphorus and potassium fertilizers. If the fertilization can be done in time, with sufficient amount of fertilizer and coordinated elements, it will not only guarantee the production of the year, but also the basis for a high yield in the next year, which is very important. The proportion of major elements in this fertilization is: phosphorus is the main factor, potassium is the second, and nitrogen is the second.

(4) Topdressing outside the roots: use foliar topdressing from April to June and September every year, dissolve fertilizer C in water, make it into the required concentration fertilizer, and spray it carefully on the leaves, branches, flowers, On the fruit, the fertilizer liquid enters the tree body through the stomata of each organ (mainly the stomata on the back of the leaves). Root topdressing is also called foliar spraying, which is a topdressing measure to supplement nutrient deficiency. The advantage is that it is simple and easy to implement, saves fertilizer and labor, has high absorption rate, quick effect, and can avoid the effect of certain elements being fixed in the soil and not easy to absorb. It is a good method for topdressing trace elements. The fertilizer liquid enters the tree body through the stomata of each organ (mainly the stomata on the back of the leaf) to increase the photosynthetic intensity and photosynthetic products, and quickly meet the tree body's need for nutrients. However, root topdressing is only an emergency measure for supplementing fertilizers, and it cannot replace underground fertilization. The commonly used fertilizers for root topdressing are flushing fertilizer and foliar fertilizer. Non-toxic pesticides cannot be mixed with acidic fertilizers; in order to avoid the neutralization of acid and alkali and lose the effect of both.

(5) Base fertilizer: From the end of September to the end of October every year, apply the alkaline hickory special formula fertilizer made by the present invention to the hickory tree. , 2.00-2.50kg for a tree in full fruit stage, and 4.00 kg for a large tree with high yield (200-250kg fresh fruit/plant).
