Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to an olive green prevention and control method using lime as a carrier. Background Art

[0002] Olive is a world-famous oil-bearing tree that can be eaten as both fruit and oil. The olive oil obtained by directly pressing its fresh fruit is the most beneficial edible oil for human health in the world today. The proportion of oleic acid, linoleic acid and essential fatty acids contained in olive oil is appropriate (not just the high or low of a certain indicator), which is similar to the proportion of nutrients contained in human milk. The digestion and absorption rate after consumption is as high as 94%. Mediterranean coastal countries such as Italy, Spain, Greece, San Marino, which have long consumed olive oil, have long been recognized by the World Health Organization as the countries and regions with the longest life expectancy per capita. The proportion of people suffering from coronary heart disease, cardiovascular and cerebrovascular diseases is the lowest. In addition to being edible, olive oil is also widely used in the fields of medicine, chemical industry, aerospace, electronics, etc.

[0003] The dry and hot valley of Jinsha River is one of the suitable areas for olives in my country. It has a large planting area, a fast development speed, and an early maturity period. It is the main olive production area in Sichuan. The dry and hot valley of Jinsha River is hot and rainy in the summer half (May to October) and cold and dry in the winter half (November to April of the following year). It is a typical summer rain climate. High temperature and humidity are more likely to breed a variety of pests and diseases, which seriously affects the production cost and oil quality of olives. Summary of the invention

[0004] The purpose of the present invention is to provide a green olive control method using lime as a carrier, which can effectively prevent and control olive diseases and insect pests, provide tree nutrition, enhance tree vigor, and enable slightly declined olive trees to recover their vigor in the same year to achieve high and stable yields.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] A green olive control method using lime as a carrier, comprising: ① quicklime 4%-6% + 0.20%-0.30% boric acid, spraying on leaves in December of the year of planting, and in February, May, July and August of the following year; ② quicklime 4%-6% + 0.8-1.2% copper sulfate + 0.20%-0.30% urea, spraying on leaves in October after fruit picking, and in April and June of the following year.

[0007] Further preferably, in step ①, 5% lime + 0.25% boric acid.

[0008] Further preferably, in step ②, quicklime 5%+1% copper sulfate+0.25% urea.

[0009] In summary, the present invention has the following beneficial effects: the green control method of the present invention can effectively prevent and control (early and middle stages of the disease) olive pests and diseases, provide tree nutrition, enhance tree vigor, and restore the mildly declining olive trees to high and stable yields in the same year. No pesticides are used, which is a green control management technical measure, in line with the national future agricultural development trend of "one control, two reductions and three basics" in China. The olive oil produced has become a high-end brand in the market, which has improved the market competitiveness of domestic olive oil. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] In order to make those skilled in the art better understand the technical scheme of the present invention, the present invention is further described in detail below in conjunction with embodiments. It will be understood by those skilled in the art that the following embodiments are only used to illustrate the present invention and should not be regarded as limiting the scope of the present invention.

[0015] Example 1

[0016] A method for controlling olive greening with lime as a carrier, characterized in that: ① 5% quicklime + 0.25% boric acid (i.e. 5 kg quicklime + 250 g boric acid for 100 kg water) is used for spraying the leaves in December of the year of planting and in February, May, July and August of the following year; ② 5% quicklime + 1% copper sulfate + 0.25% urea (i.e. 5 kg quicklime + 1 kg copper sulfate for 100 kg water, and 250 g urea is added after the preparation), which is used for spraying the leaves in October after fruit picking and in April and June of the following year.

[0017] Example 2

[0018] A method for controlling olive greening with lime as a carrier, characterized in that: ① 4% quicklime + 0.30% boric acid (i.e. 5 kg quicklime + 300g boric acid for 100 kg water) is used for spraying the leaves in December of the year of planting and in February, May, July and August of the following year; ② 6% quicklime + 0.8% copper sulfate + 0.20% urea (i.e. 6 kg quicklime + 0.8 kg copper sulfate for 100 kg water, and 200g urea is added after the preparation), which is used for spraying the leaves in October after fruit picking and in April and June of the following year.

[0019] Example 3

[0020] A method for controlling olive greening with lime as a carrier, characterized in that: ① 6% quicklime + 0.20% boric acid (i.e. 6 kg quicklime + 200 g boric acid for 100 kg water) is used for spraying the leaves in December of the year of planting and in February, May, July and August of the following year; ② 4% quicklime + 1.2% copper sulfate + 0.30% urea (i.e. 4 kg quicklime + 1.2 kg copper sulfate for 100 kg water, and 300 g urea is added after the preparation), which is used for spraying the leaves in October after fruit picking and in April and June of the following year.

[0021] Through several years of experiments, no other pesticides are needed from young trees to adult fruit-bearing trees, which can effectively prevent and control diseases and pests of olives, ensure the healthy growth of trees, achieve stable and high yields, and have no side effects when used every year. It is a green prevention and control management technical measure for olives. Lime is cheap, which reduces production costs and conforms to the national development trend of "one control, two reductions and three basics" in China's future agriculture. The olive oil produced has become a high-end brand in the market, which has improved the market competitiveness of domestic olive oil. At present, it has been promoted and applied in 10,000 acres. The main olive producing areas in my country have a summer rain climate, high temperature and high humidity are prone to diseases and pests. The soil in most olive planting areas is acidic, and the effective calcium and boron content in the soil is low, which is not conducive to the growth of olives. This invention can be promoted and applied in other olive planting areas.

[0022] like Figure 1 As shown, use quicklime + boric acid to spray the olive tree leaves. Figure 2 As shown in the figure, quicklime + copper sulfate + urea is used as a modified Bordeaux mixture to spray the olive tree leaves. Figure 3 As shown in the figure, before the prevention and control in 2023, the olive trees were attacked by pests and diseases, with fewer leaves and abnormal leaf color, such as yellowing and spots. After a year of green prevention and control, the pests and diseases of olives were effectively prevented and controlled, and the olive trees were lush and without yellowing and spots. It not only prevented diseases, but also restored the tree vigor, turning declining trees into high-yield trees. Figure 4 As shown in the picture, the circled spots on the leaves are the spots before lime treatment. They were circled with a pen before lime treatment. After a week, the spots were controlled and did not expand, and the leaves with mild symptoms returned to normal. If the expansion of the spots was not controlled, the leaves would turn black and yellow and finally fall off.

[0023] Principle: ① Olive trees like alkalinity and have a strong tolerance to high concentrations of lime. Olive trees are "nitrogen-loving and calcium-loving". Lime water provides calcium for olive trees. Lime has a strong adsorption capacity and can be attached to leaves for a long time, so that olive scale insects and beetles cannot parasitize on them. Leaves and trunks with lime are not palatable to insects, and they do not like to eat them, which effectively prevents pests.

[0024] ②Copper preparations are a good means of disease prevention and control. Bordeaux liquid is used to prevent and control diseases of many fruit trees. We have improved Bordeaux liquid to specifically meet the needs of olive trees.

[0025] ③ Most of the soil in my country lacks boron. Boron can improve the resistance of fruit trees in the dry season. Calcium and boron can promote the growth of growth points at the same time, thereby promoting the absorption of nutrients by the roots. Through experiments, after spraying for a week, new leaves can be seen growing on the tree, which promotes growth faster than any other elements and combinations. The combination of urea and Bordeaux liquid can prevent diseases and insect pests and enhance the vigor of weak trees.

[0026] ④ Using the two alternately can prevent the occurrence of antagonism between nutrients, thereby ensuring that the fruit trees have comprehensive nutrition.

[0027] The above embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, such modifications are protected by the patent law as long as they are within the scope of the claims of the present invention.
