Description

An irrigation method to improve environmental tolerance and quality of plants

technical field

The invention relates to a plant irrigation method, in particular to an irrigation method for improving plant environmental tolerance and plant quality, and to plants using the method.

Background technique

Zinc is an essential micronutrient for normal growth, development and health of plants and humans. Zinc deficiency in large areas of agricultural land is known to result in severe reductions in crop yields and nutritional quality of food crops. Zinc deficiency remains an unrecognized or underestimated condition and is not addressed in many countries. Therefore, there is an urgent need to understand and address zinc deficiency in these countries for the benefit of crop production and human health. Zinc is also particularly important for crops to have better tolerance to various stress factors such as drought, high temperature and salt conditions. When the supply of zinc available to plants is insufficient, crop yield and crop product quality will be impaired. In plants, zinc plays a key role in many important biochemical pathways as a structural component or regulatory cofactor of many different enzymes and proteins.

Iron is a component of the catalytic portion of some important oxidoreductases. In plants, iron exists on the electron transfer bond of hemoglobin. In the catalytic redox reaction, iron can become oxidized or reduced, that is, it can reduce or increase an electron. Iron is not a component of chlorophyll, but when iron is deficient, the lamella structure of chloroplasts changes greatly, and even chloroplasts disintegrate in severe cases, and leaves will lose chlorosis when iron is deficient. It can be seen that iron is essential for the formation of chlorophyll.

Copper is one of the seven trace elements necessary for the normal life activities of plants, and it participates in various metabolic reactions in the process of plant growth and development. Copper is a component of polyphenol oxidase, ascorbate oxidase, cytochrome oxidase, etc., and participates in the redox process in plants. It is also present in the plastocyanin of chloroplasts and is involved in electron transport for photosynthesis. The fruit trees are copper-deficient, the leaves on the top tips are clustered, and the leaves and fruits are all faded. In severe cases, the top shoot dies and gradually expands downward.

In addition to direct damage caused by external factors such as plant pests or lack of basic nutrients, the growth of a plant is affected by the response of the plant itself to external environmental stressors. When subjected to such stress factors, plants exhibit a variety of mechanistic responses as protective measures, with resulting adverse effects on growth, development and reproduction. Significant loss of quality and yield is often observed. There is a need for methods for addressing environmental stress experienced by plants in order to increase plant tolerance to environmental stress and improve plant crop quality and yield, especially during the routine irrigation of plants.

Contents of the invention

The object of the present invention is to provide an irrigation method for improving plant environmental tolerance and quality, which is used to improve plant quality and yield.

In order to achieve the above objects, the present invention provides an irrigation method for improving plant environmental tolerance and quality, applying micronutrients and/or plant activators and/or plant hormones and/or growth retardants containing active ingredients in irrigation water and/or cytokinin treatment of plants and/or plant growing areas and/or plant propagation material.

Further, the micronutrients containing active ingredients are selected from active ingredients containing at least one metal ion.

Furthermore, the micronutrients containing active ingredients are selected from the group consisting of zinc thiadiazole, mancocopper, mancozeb, ferbam, Bordeaux mixture, copper sulfate ternary, and copper oxide.

The above-mentioned micronutrients containing active ingredients have fungicidal properties and are used to control various plant diseases.

Plant activators such as activated esters, thiabendazole, thiadiazolin, and benzothiadiazole can be used to control fungi and bacteria, with both protective and therapeutic effects, and can activate their defense mechanisms against pests or diseases to protect plants.

Plant hormones such as gibberellic acid, clofibric acid, tripropionic acid, naphthol, potassium naphthenate, sodium naphthenate, etc. can be used to promote plant growth or inhibit plant growth. Additive application of auxin to plant roots via dropper or sprinkler irrigation can also inhibit insect damage.

Growth retardants such as chlormequat, tetracyclazole, paclobutrazol, flusulam, etc. are used to inhibit plant growth and stimulate flowering, especially for ornamental plants or orchard plant crops. Application by soil infiltration or soil injection can reduce seedling growth, and can also achieve effects such as improved drought stress resistance, enhanced root development, protection from fungal and bacterial pathogens, and greener and taller branches and leaves.

Cytokinins such as kinetin, benzyl adenine, zeatin, etc., can promote cell division, promote fruit setting, and promote callus germination, as well as delay the senescence of detached leaves and cut flowers, induce bud differentiation, development and increase The effect of stomatal opening.

Further, neonicotinoids such as thiamethoxam are also included. Neonicotinoids are beneficial to plant health. They can make plants emerge faster, produce higher yields, improve protein content, develop root systems, greener and taller branches and leaves, increase leaf area, and mature and bloom faster. In particular, it can enhance the tolerance of plants to the environment by enhancing the activity of functional proteins in plants. In addition to being used as a pesticide, it can also be used as a seed treatment to stimulate plant growth.

Further, simultaneous and/or sequential application of one or more other agricultural compounds and/or plant nutrients and/or plant fertilizers for improving environmental tolerance and plant quality is included.

Further, other agricultural compounds such as herbicides, insecticides, bactericides.

Further, these plants are ornamental plants and orchard plant crops.

Further, the plants using the method of the present invention can better adapt to drought, flood, low pH value, high soil salinity, high temperature, low temperature, air pollution, soil pollution or pests or any combination thereof.

Further, the irrigation is drip irrigation, sprinkler irrigation, spring irrigation, underground irrigation, seepage irrigation, surface irrigation, manual irrigation or partial irrigation or any combination thereof.

The beneficial effect of the invention is that the irrigation method can improve the resistance of ornamental plants and plant crops in orchards. Especially environmental tolerance, while improving the quality and quality of plants, increasing ornamental and fruit setting rates.
