Description
Technical Field
The invention belongs to the technical field of agriculture, and particularly relates to a comprehensive management method for flower promotion and fruit retention of macadimia nuts.
Background
Macadamia nut is also called macadamia nut, is rich in nutrition, fine and smooth in taste and excellent in flavor, and enjoys the reputation of being "the dried fruit is queen". In recent years, as the planting area of macadimia nuts is continuously enlarged and the yield value is rapidly increased, the macadimia nut planting is listed as a key industry for developing poverty-weakening and hardness-attacking actions in a new stage.
Macadamia nut flowers are inflorescences with a general shape, amphoteric flowers and stamen first-maturing flowers, are generally self-pollinated, but have a large degree of self-sterility. In production, poor pollination and fertilization is recognized as one of the important reasons of low fruit setting rate and low yield of the macadimia nuts, and pollen activity and stigma pollination are the prerequisite guarantee for the fruit trees to complete pollination and fertilization. Most macadamia nuts bloom in large quantities every year, but only 0-2% of flowers grow into fruits finally, and the rest more than 98% of flowers fall off successively in the post-flowering (early stage) or young fruit development stage (later stage), so that excessive flower and fruit fall affect the yield and benefit and can weaken the tree vigor of fruit trees. The main reasons for early flower and fruit drop are poor fertilization or no fertilization, or embryo dysplasia; the main reason for fruit drop in the later period is that the tree has less nutrient substances stored therein and insufficient supply of fruit; or imbalance in the ratio of vegetative growth to reproductive growth; or pest damage, etc.
Disclosure of Invention
Aiming at the defects of the macadimia nuts, the invention provides a comprehensive management method for promoting flower and protecting fruit of the macadimia nuts, which solves the problem of excessive flower and fruit drop of the macadimia nuts, improves the yield, increases the benefit and keeps the trees healthy and strong.
The invention is realized by the following technical scheme:
a comprehensive management method for flower promoting and fruit retention of macadimia nuts comprises the following steps:
(1) spraying 1.0-1.5L of paclobutrazol 1000-fold liquid and 1.0-1.2L of gibberellin 2000-fold liquid with the concentration of 25% on each fruit tree in the early stage of flower bud differentiation of macadamia nuts in 10-11 months, and simultaneously applying 10-20 kg of organic fertilizer and 1kg of compound fertilizer to control tips and promote flowers;
(2) spraying 0.8-1.0L of compound sodium nitrophenolate 2000 times liquid, 0.5-0.8L of 0.1% concentration amino acid foliar fertilizer, 0.5-0.6L of 0.1% concentration borax and 0.2-0.5L of 0.1% concentration potassium dihydrogen phosphate to each fruit tree at the beginning of 2 months in the flowering period of macadimia nuts;
(3) spraying 0.8-1.0L of compound sodium nitrophenolate 2000 times liquid, 0.5-0.8L of brassin 2000 times liquid, 0.5-1.0L of 0.1% concentration borax, 0.5-0.8L of 0.2% concentration amino acid foliar fertilizer and 1.0-1.2L of beeswax water in the full-bloom stage of macadamia nuts at the bottom of 2 months;
(4) in the initial stage of fruit setting of the macadimia nuts in the early 4 months, 1kg of compound fertilizer and 0.2% of amino acid foliar fertilizer of 0.5-0.8L are applied to each fruit tree.
The invention improves the activity, stigma receptivity and fruit setting rate of macadamia nut pollen by applying an exogenous fruit retention agent.
Spraying paclobutrazol and gibberellin at the early stage of flower bud differentiation, promoting bud tillering, improving plant cell activity and improving tree carbohydrate level (starch and soluble sugar content), wherein the gibberellin has the most prominent effect of accelerating cell elongation, can improve the content of auxin in a plant body, has a promoting effect on cell division, and can promote cell expansion, so that the macadamia nut can germinate and bloom more; meanwhile, organic fertilizer and compound fertilizer are applied to promote the growth of the nut plants and improve the disease resistance of the plants.
Spraying compound sodium nitrophenolate in the initial flowering period and the full flowering period, and after the compound sodium nitrophenolate is absorbed by plants, the C/N ratio of the plants can be adjusted, so that the plants have disease resistance, the plants are robust, the stress resistance of the plants is enhanced, the growth speed of macadamia nuts can be accelerated, the dormancy of flower buds is broken, the stigmatization is improved, the flower and fruit dropping is prevented, and the yield of the nuts is improved. Brassinolide is one of steroid compounds with high biological activity, is widely present in plants, and can promote vegetative growth and facilitate fertilization in each stage of plant growth and development. The artificially synthesized brassinolide has high activity, can be absorbed by leaves, stems and roots of plants and then is conducted to the acting parts, so that the activity of RNA polymerase can be increased, the content of RNA and DNA can be increased, the potential difference of cell membranes and the activity of ATP enzyme can be increased, and the effect of auxin (gibberellin and paclobutrazol) can be enhanced. At very low concentrations, brassin significantly increases vegetative growth and promotes fertilization in plants.
The beeswax water can attract bees, thereby promoting pollen propagation and improving pollination and fertilization; the foliar fertilizer is used for promoting the photosynthesis of plants and improving the fruit setting rate.
As a further improvement of the invention, the compound sodium nitrophenolate is prepared from 5-nitro-o-methoxy sodium phenolate, o-nitrophenol sodium and p-nitrophenol sodium according to the mass ratio of (0.8-1.2) to (2-3) to (3-4).
As a further improvement of the invention, the organic fertilizer is prepared from the following components in parts by weight: chicken manure 6070 parts, calcium magnesium phosphate 5-10 parts, potassium sulfate 3-5 parts, bone meal 3-5 parts, urea 5-10 parts, lime 0.5 part and boron, iron and zinc trace elements 0.5 part.
As a further improvement of the invention, the compound fertilizer is prepared by mixing a nitrogenous fertilizer, a phosphate fertilizer and a potash fertilizer according to a mass ratio of 15:8: 20.
The invention has the following beneficial effects:
according to the management method, exogenous agents are used for promoting bud tillering and improving plant cell growth in the flower bud differentiation period of the macadimia nuts, the flowering rate and the plant resistance are improved, agents capable of promoting the plant growth speed are sprayed in the initial flowering period and the full flowering period, flower bud dormancy is broken, stigma pollination is improved, and meanwhile, bee wax water is sprayed to further improve the pollination rate, so that the pollination fertilization and fruit setting rates of the macadimia nuts can be effectively improved, and the fruit yield is improved.
