Description

The present invention relates to a large lemon (referred to as jumbo lemon) that can be grown faster than a normal lemon, and a method for cultivating it.
Today lemons are widely incorporated into our daily lives, from flavors to cosmetics and cosmetics.
Currently used lemon (Citrus limon) prefers a warm climate with relatively little precipitation, and in Japan it is often cultivated in the western region of the Kanto region. In addition, the cultivation of lemons is characterized by the preference for drained soil containing a large amount of organic matter and requiring more fertilizer than other fruit trees.
For example, Hayashi Yasaka Editor, Yamato Valley Co., Ltd., published in 1988 “Japanese Trees”, p. See 375.

  Lemons are often discussed for effective intake of vitamin C contained in large quantities in fruits reflecting the recent health boom. For this reason, lemons imported not only from Japan but also from overseas have been used in large quantities. However, since many of the lemons imported from overseas take a long time to be sold to consumers, the surface treatment of antifungal agents (OPP, TRZ, Imazaril, etc.) Used within the standards). For this reason, when using it as an edible, it is necessary to peel off the lemon skin or use it after thoroughly washing the surface of the lemon with water.

In consideration of such a situation, the present invention adds a breakthrough improvement to lemon cultivation. In other words, it is characterized by increasing lemon cultivation and promoting cultivation by increasing the lemon size (jumbo lemon) and shortening the cultivation period.
When cultivating jumbo lemons, it is necessary to grow to a large size, so it usually takes a long time for growth. However, when the method of the present invention is adopted, conversely, jumbo lemons are produced in a short period of time. Can be cultivated.

  As a result of earnest and detailed studies aimed at increasing the amount of lemon grown and promoting the cultivation, it was found that the violet five-valve lemon flower that blooms every spring has a nutmunk (Citrus natsudadai) It is related to the cultivation of jumbo lemon, which is characterized by pollinating and growing with the oshibe flower.

That is, the gist configuration of the present invention is as follows.
(1) A jumbo lemon cultivating method characterized by pollinating the stalks of a Natsumikan flower on a stalk of a lemon flower and cultivating it quickly.
(2) The jumbo lemon cultivation method according to (1), wherein the soil around the lemon tree is covered with an artificial mat.
(3) Jumbo lemon cultivated rapidly by the cultivation method according to claim (1) or claim (2).

  The present invention grows a fruit having a size of about 6.5-7.5 cm (jumbo lemon) and a small green color similar to the current lemon, rather than the current elliptical lemon size of about 4-5 cm in diameter. It was discovered that this jumbo lemon can be harvested in a shorter period of about 15-40 days than the current lemon maturity period until it matures into a bright yellow jumbo lemon.

The schematic diagram of FIG. 1 includes (1) the current lemon (it takes about 7 months to mature into a bright yellow lemon) and (2) jumbo lemons cultivated according to the present invention (until they mature into a similar bright yellow, It is possible to grow 15-40 days shorter than the current lemon maturation period.) In addition, the jumbo lemon of the present invention has an elliptical shape, but has a slightly round shape as compared with the current lemon, and has a feature similar to that of a nutmican.
Such a jumbo lemon of the present invention has a volume that is 1.5 times or more larger than that of the current lemon, and a short period of about 15 to 40 days until it matures from a small green fruit to a bright yellow lemon. It can be harvested in between, and it is characterized by a large utilization effect of rapid cultivation of lemon.

The contents of the present invention will be specifically described below.
FIG. 2 schematically shows the lemon cultivation method of the present invention. The lemon tree of (3) should be a lemon tree that has passed about 5-10 years. (4) is most suitable for the growth of lemon when planted in a well-drained soil containing a large amount of organic matter. In addition, lemon trees are weak in cold resistance, so a sheet of green artificial grass (about 1 cm thick) is placed on the soil as shown in (5) to prevent winter cold resistance and summer soil. It is important to take measures to help prevent the drying of the soil, and it is better to use such sheets to protect the soil of the lemon tree. In other words, it is sufficient that the drainage is good and the soil of lemon trees can be protected by preventing cold resistance and preventing drying of the soil.

  The enlarged view of (6) shows, as shown in (6-1), the state of the tip of the central part of the lemon blossom that pollinates the Oshibe of Natsumikan of (6-2) (arrow of (6-3)) Is schematically shown). In other words, pollination of Natsumikan Oshibe on the flower syllabary of the lemon flower enhances the flowering property by placing the Natsumikan flower directly on the lemon flower stake or by attaching it to the lemon flower pillar via a barnyard, etc. This is very important. In addition to Natsumikan pollen, citrus pollen such as Iomikan, grapefruit, decapon, Hassaku, and Amanatsu may be used.

  After pollination to lemon style, it is better to apply bone powder, oil cake powder, solid fertilizer, organic compound fertilizer, compounded fertilizer, or humus throughout the year at 3-4 month intervals to steadily grow the fruit. .

For short-term cultivation of such jumbo lemons, it is best to use Natsumikan pollen, but it is also possible to use citrus pollen such as Iomikan, Grapefruit, Decopon, Hassaku, Amanatsu, etc. .
In addition, by using seeds present in jumbo lemons and germinating and growing these seeds, it is possible to supply lemons that have a large lemon size and can be cultivated in a short period of time.

  Using a lemon tree that has been about 10 years old in November before the arrival of winter, the proportion of solid fertilizers such as bone meal and oil cake, organic compound fertilizer (Chisso (7): Linsan (12): Potash (6) The compounded fertilizer and humus were applied to the soil at a ratio of 1: 1: 0.5: 1. On this soil, a green artificial turf (approx. 1 cm thick) sheet is laid as shown in Fig. 2 (3), and measures are taken to help prevent cold weather in winter and dry soil in summer. It was.

Lemon flowers bloom from late April to early May of the following year. Natsumikan flower was pollinated by the method of the method shown in the detailed view of (4) in FIG.
In addition, fertilization was conducted three times in April, August, and November throughout the year with organic solid fertilizers such as bone meal and oil cake, organic composite fertilizers, compounded fertilizers, or humus.

  In late October, a large green lemon began to turn yellow near the center. In late November, it was matured into a bright yellow jumbo lemon and harvested. On the other hand, regular lemons began to turn yellow in the middle of November, starting from the middle. In this experiment, it was possible to harvest jumbo lemons in a short period of 30 days.

  In order to respond to the effective intake of vitamin C contained in large quantities in fruits reflecting the recent health boom, the present invention has a volume that is 1.5 times larger than the current lemon, and It can be harvested in a short period of about 15-40 days until the small green fruit matures into a bright yellow lemon, and the effect of rapid lemon cultivation is great.

It is the schematic diagram which compared the current lemon and the jumbo lemon cultivated by this invention. It is a schematic diagram which shows the cultivation method of the lemon of this invention.
