Description
Technical Field
The invention relates to the technical field of plant cultivation, in particular to a method for promoting mango young She Yiyang to be transformed into autotrophic by fertilization.
Background
The change of mango leaf color can be divided into three stages of a bronze stage, a light green leaf stage and a green leaf stage, wherein a new leaf is initially the bronze stage, the leaf color is purple red, then the new leaf enters the light green leaf stage, at the moment, the leaf color is green but light, and finally the new leaf enters the green leaf stage. The young mango leaves have low chlorophyll content and weak photosynthetic capacity, can not provide nutrition for growth and are in a heterotrophic state. As the leaf matures, the pigment content, morphological structure and the like of the leaf change, the chlorophyll content increases gradually, and the photosynthetic capacity also increases.
Mineral elements are necessary for growth in the growth process of plants, and play an important role in the growth process of plants, and excessive or insufficient mineral elements can influence the normal growth of plants. Mineral elements can be divided into major elements and trace elements according to plant growth demand, wherein the major elements are carbon (C), hydrogen (H), oxygen (O), nitrogen (N), phosphorus (P), potassium (K) and the like, and the trace elements are iron (Fe), magnesium (Mg), zinc (Zn) and the like. Nitrogen, phosphorus and potassium are considered as three elements in the plant growth process and form the basis of plant vital activities. Iron and magnesium are also essential trace elements for plants, wherein iron is the first place of essential trace elements for plants, and can have a great influence on chlorophyll synthesis.
Current technical research:
1. the research on the relation of the chlorophyll content, the specific leaf weight and the photosynthetic rate of the mango leaves shows that different leaf ages have influence on the chlorophyll content and the specific leaf weight of the mango leaves on the photosynthetic rate of the mango leaves and are in very obvious positive correlation.
2. The photosynthetic characteristics of the young leaves, the fully-developed young leaves and the mature leaves of the ginkgo are researched, and the result shows that the photosynthetic capacity of the mature leaves is strongest, the fully-developed young leaves are She Ci, and the young leaves are smallest.
3. The research results of the influence of the mixed application of different nitrogen, phosphorus and potassium fertilizers on the chlorophyll content of the Ficus simplicissima lour show that after the mixed application, the chlorophyll content of the Ficus simplicissima lour can be remarkably improved, the influence effect of the nitrogen fertilizer is maximum, the phosphorus fertilizer is secondary, and the potassium fertilizer is minimum.
4. As a result of applying nitrogen, phosphorus and potassium organic fertilizers with different proportions to potatoes, it is found that the best chlorophyll content is improved by applying 235.5-251.3 kg/hm2 nitrogen, 121.9-123.6-kg/hm 2 phosphorus and Shi Jia 174.5.5-190.2-kg/hm 2 organic fertilizers 37-38 kg/hm 2.
5. The effect study of different fertilization treatments on the chlorophyll content of the leaf of the two-year-old Nanguo pear shows that the chlorophyll content can be increased along with the increase of the amount of nitrogenous fertilizer and phosphate fertilizer, and the chlorophyll content is in a trend of rising and then falling along with the increase of the amount of potash fertilizer.
6. The annual seedling sowing of the red oaks in North America is taken as a test object, and the treatment results of different fertilizers and fertilizing amounts show that the different fertilizing treatments improve the chlorophyll content of the red oaks in North America to a certain extent, and in a certain range, along with the increase of the fertilizer application amount, the chlorophyll content is correspondingly increased, and the influence of the nitrogenous fertilizer and the compound fertilizer on the total chlorophyll content reaches an extremely remarkable level.
7. The short-branch Fuji and Gala apple trees are used as test materials, shi Jia 0.5.5 kg of fixed values are adopted, and nitrogen fertilizer, phosphate fertilizer and organic fertilizer are adopted to carry out 3-factor 3-level secondary regression orthogonal test design, so that research results show that the application amounts of nitrogen, phosphorus and organic fertilizer are respectively 0.5 kg/plant, 0.4 kg/plant and 2.5 kg/plant, the chlorophyll content of mature-stage leaves is the highest, and the senescence of mature-stage leaves can be delayed to a certain extent.
8. The method takes 1-year-old Alnus trabeculosa seedlings as research materials, and adopts orthogonal combined fertilization tests of applying different amounts of nitrogenous fertilizer, phosphate fertilizer and potash fertilizer to determine the total chlorophyll content, and results show that different fertilizer proportions have different effects on the total chlorophyll content of Alnus trabeculosa seedlings, and the ratio of the nitrogen, phosphorus and potassium fertilizer which is most suitable for increasing the chlorophyll content is 0-0.2:0.6:0.1-0.4.
9. The optimal fertilization formula for improving the leaf green content of the camellia oleifera in the forest is urea 1%, dipotassium hydrogen phosphate 0.44% and potassium chloride 0.27%.
10. The leaf of ficus microcarpa is taken as a research object, the influence of different element fertilization on the chlorophyll of the leaf of ficus microcarpa and the mass fraction of the leaf nitrogen is discussed through different fertilization treatments (single fertilization of N, PK and NPK), and the result shows that the different fertilization treatments can obviously influence the contents of chlorophyll a and chlorophyll b, and the mixed fertilization effect of nitrogen, phosphorus and potassium elements is larger than that of a single effect.
11. Nii shows that after nitrogenous fertilizer is applied to peach, chlorophyll content in leaves of peach is increased, photosynthesis of the leaves is also enhanced, and carbon assimilation rate is also increased along with the increase of nitrogen application amount.
12. The research on spraying the phosphate fertilizer on the leaf surfaces of the 'summer black' grape shows that the spraying of the phosphate fertilizer has obvious effect of promoting the growth of chlorophyll on the leaf blades of the 'summer black' grape.
13. Research on spraying the iron fertilizer on the blueberry leaf surfaces shows that the application of the iron fertilizer has a good effect on improving the chlorophyll b content in the blueberry leaf, so that the photosynthetic pigment content in the leaf is obviously increased.
14. The research on the influence of the magnesium fertilizer on the chlorophyll content of the leaves of the Taiwan green dates shows that the magnesium fertilizer can obviously improve the chlorophyll content of the leaves.
15. A correction test for the mangoes suffering from iron deficiency and green loss shows that the application of ferrous sulfate and amino acid iron solutions can improve the active iron content and the total iron content of the leaves of the mangoes suffering from iron deficiency and green loss to different degrees.
At present, fertilization is not used for promoting the conversion of mango young leaves from heterotrophic to autotrophic literature or other reports, and an orchard using the method is not used in actual production.
