- what kind of lemon seed?
1. Yulik
Also known as the oil rick, oil liga, which is the most widely cultivated species in the world today, the fruit elliptical to fall eggs, the fruit medium, 90-160g long elliptical with a single fruit weight, the top with a nipple bulge, the base with a blunt circle and a radioactive gutter. Leather is yellow, the oil is large, the skin is thin under normal management and the core is low。
Fino
It originated in spain and is based in australia. The fruit is medium in size, spherical or elliptical, light or yellow, thin and smooth, high acid。
Genoa
From genoa, italy, the skin is smooth and thin, the shape of the fruit is more round, the neck is shorter than the yogurt, the lemon acid content, the juice rate, and the thickness of the bark is comparable to that of the yogurt。
4. Beijing lemon
Also known as the sons of bitches who had been brought back to the united states in 1908 in the outskirts of beijing and who had been brought back to the united states. It is sour, tastes bitter, has soft internal structures, is resistant to heat and cold, and has thin fruit skins that are unsustainable。
Ii. Lemon seeding methods
1. Growing branches
The lemon grows strongly, smoking three to five times a year, pumping lots, flowers, results, long, thick and productive。
Spring 2-april: new beginnings are more uniform and numerous, with small, fine and neat branches, most of them splitting into buds, forming the resulting parent branches。
Summer may-july: the branches grow strong, grow strong, absorb more nutrients, have green leaves, have a tributary and are easy to form。
Autumn 8-october: most of the following year's results are the mother branches, which are affected by the flowering results, with smaller, long branches and underdeveloped growth。
Winter 11th to january of the following year: low-temperature and low-nutrient nutrients, low-intensity, undernourishment, prone to yellowing。
2. Modified points
The main purpose of the larvae and the primary result tree trims is to develop tree coronal skeletons so that they can be expanded more quickly and better. The larvae trim is suitable in the winter, and should be provided with the care and necessary short cut during the growing season, and leaves and branches should be kept as far as possible。
Earnings: young trees should grow, and after the seasons of branches, the rest, except for the eight to ten pieces reserved for the long ones. The length of 20-25 centimetres is appropriate, and the canopy is enriched, with early and multiple branches, so that the canopy can be expanded as soon as possible。
(b) the timely elimination of long branches, which disrupt the shape of trees and waste nutrients, should be eliminated。
Rattling: it is appropriate to use a pull-and-support approach to the strong and strong branches. (b) stronger branches are pulled down, with a large cut-off of 40°-50°, and the adoption of a pull-up measure for the larvae can lead to an earlier one to two years of outcomes。
Scrambling: the seedlings can be sprung in the summer, i. E., an autumn, to facilitate the expansion of the tree crown as soon as possible。
Summer mowing: strongly growing young trees with more hair. Since the long and strong summer seasons are not easy to draw, and do not favour the separation of buds, they were sprung and trimmed between may and july. As a result, they were completely cut in early august, resulting in more swings between late august and early september. Most of these autumns bloom the following year。
(b) cultivation of branches: the small branches usually drawn within the canopy shall be kept as long as they are not twigs or twigs. These branches are often good outcomes for the larvae。
• plumbing leeches: the buds and fruit that appear in the weak trees before the planned fruit are to be removed in time to facilitate the nutritional production of the trees and to produce the crowns of the results as soon as possible。
Plumbing fruit
Zinc sulphate was first applied 0. 2 per cent after spring sprouts, 0. 5 per cent urea + 0. 2 per cent percium phosphate + 1 per cent potassium sulphate once before flowering, 0. 4 per cent ~0. 5 per cent urea ~0. 3 per cent ~0. 3 per cent potassium phosphate and precipitating agent (triple green leaf), and 0. 3 per cent urea + 3 per cent percussion + 0. 5 per cent potassium sulphate during fruit expansion. When the larvae is stabilized, soil moisture is maintained, and it is critical that water be poured out 10 days before spring。
4. Fertilizer management
The purpose of fertilization of unresulting larvae is to promote the early growth of the canopy and its early commissioning. However, care should be taken to prevent over-fertilization and over-nutrition and to avoid delays in the flowering of results. The fertilisation of fertilized larvae, which is based on the principle of “indulgent, thin application”, is performed three times a year:
In mid-february, the first fattening, 25 per cent of the year's total, should be 800 - 1,600 kg of urea per acre, 8 - 16 kg of calcium per phosphate and 8 - 16 kg of compound fat。
The second one, at the end of june and the beginning of july, accounted for 50 per cent of the year's total, with 1,600-3200 kg of urea per acre, 16 kg of calcium per phosphate and 8-10 kg of compound fat。
The third one, which was 25 per cent of the year's total, took place between the end of august and the beginning of september. It was 800 - 1,600 kg of urea per acre, 8 - 16 kg of calcium per phosphate and 8 - 16 kg of compound fat。
In the light of all of today's events, the famous lemon varieties, both yulik and fino, have to take into account the ecological conditions in which they are grown。
