I. Use of ethylene and polyazole for flower promotion
The slow growth and development of the dragon's eyes during the winter's low-temperature and dry conditions, which consumes large amounts of nutrients in the tree body, are extremely detrimental to the thawing of the flowers and require control over the onset of the winter to ensure their normal flowering. The use of ethylene and polyecstasy controls can yield better results。
Production practices have proven that the use of ethylene and polyecstasy can kill winters, inhibit the onset of winters and promote the rapid and sophisticated development of young autumns. They are also low-cost, easy to use, easy to make and easy to control。
More than 90 per cent of the ethylene tablet could be sprayed in mid-november-early december; in mid-december, a multi-acting acetylene or ethylene was sprayed once. If the first two do not work as well, another multi-utilized euphoria can be sprayed in early january of the following year, depending on the onset of winter。
Note: the concentration of ethylene tablets is 50 kg water adhesive to ethylene 31-37 ml, and the concentration of polyoxidium tablets is 50 kg water adhesive to polyoxin 165-330 g powder. It is used in a manner that adjusts the amount of medicine to climate and tree patterns, in which the trees are strong and warm, and in which the concentrations are higher and lower。
Ii. The use of hormone nuts and extra-root fatting
The flowering of the eye and the growing growth of the fruit produce are consuming a great deal of nutrients, so care must be taken to supplement the nutrients of the tree body by applying the pyrophoric fertilizer, which is one of the effective methods of supplementing nutrients during the hysteria of the eye, while the use of hormones increases sit-in rates and increases yields。
The 2,4-d5 ppm (i. E., 1 g to 200 kg) and chromosomal 20-50 ppm (i. E., 1 g to 20 to 50 kg) were sprayed with precautionary fruit after the bouquet (green to soybeans) and 500 times the microfat of amino acid. Spraying 2,4-d 5 ppm with chromosomal 20 ppm or 25-30 ppm with deprecative fruit at about 20 d before the second physiological fall。
The use of hormonal cone should be carried out with strict attention to the use concentration, in particular 2,4-d, which should not exceed 5 ppm, and which seriously affects the following year's results if the concentration is used over and above the general result of the fall or deformity, as well as the finening and curling of the tectonic leaves。
The inclusion of 0. 2 per cent of potassium phosphate in each case of pest control spray or hormonal cone would effectively increase sitting rates. Or application of “triple” (synthetic potassium phosphate+hormonal+pesticide) can be used to protect both the nuts and the pests。
Iii. Rational application of fertilizers
Dragon-eyed fruit fats are applied rationally according to the amount and shape of the tree, and young trees with little, strong trees and fertile soil can be dispensed with less; and mid-age trees with many of the trees, weak trees, must be fertilized once after the second physiology has failed。
If fertilizers are applied in a dry weather in order to ensure the absorption of fertilizers, the application of fertilizers is applied to trees in the amount of 50 to 100 kg of cedars and 0. 5 to 0. 75 kg of potassium oxide, 0. 5 to 0. 75 kg of calcium perphosphate, or to potassium oxide in the amount of 0. 5 kg and compound fat in the amount of 0. 5 to 0. 75 kg for water in the amount of 100 kg。
Where appropriate, the application of low-output trees can be reduced, and if successive droughts require water to keep the soil humid in a timely manner, a particularly high number of trees are expected to be able to apply the same amount of fertilizer as the previous one during the chromosomal period。
To combat trichomoniasis
The main pests in the eye are frosting, larvae, larvae and roll moths, especially those that cause serious damage。
1. Little ashflies
The larvae of the larvae larvae enters from the centre of the fruit and each larvae can cause 2 to 3 small fruites; however, the larvae ceases to invade when the kernel is covered. Most of the older larvae melt in the cracks of the tree, and then they fall into bad shape。
The drug, which is mainly designed to combat small-scale ash butterflies and also to treat red spiders, tweeds and twigs, is administered 5,000 times more efficiently when the effects are green beans, or 80 per cent of trichlorfon 800 times more than 500 times more insecticidal。
2. 蝽蟓
It is mainly for the benefit of young leaves, ears and young fruit, which are dried up and taken off, and which, in the event of serious damage, results in the loss of the eyes of the dragon。
Rolling moths
The larvae eat the larvae to the detriment of the young, and the larvae eat the larvae, resulting in a large loss of the larvae and even the loss of the harvest. In mid-april, when the fruit plant grew to the size of peanut grains, the moth larvae could also enter the fruit at a time when it was more likely to be found in the hole。
Based on the characteristics of the three pests above, it is necessary to control the prophylactic period for the development of the dragon eye。
During the second physiological fallout period, the fruit grew up to 3,000 times more than or 90 per cent more than 800 times trichlorfon and 500 times more than or 3,000 times faster than the vermin. The spray was based on the control of leaf moths and the treatment of pests such as the remaining vermin。
Any of these pesticides can be sprayed before and after the core is formed and when the fruit thumbs are large, but the effects are better in kung fu, in efficient use, and in fast use, the spray is mainly used against moths and other pests。
At the time of the three sprayings mentioned above, when pests occur, they will also need to be treated on a case-by-case basis to achieve high-yield quality。
4. Combating froste
Long-eyed frost is the most serious disease in the eye, during the development of the fruit and during transport, causing large numbers of flowers and fruit; the fruit has suffered a lot. The appearance of a tan-coloured disease from the gourmet, which spreads rapidly at high temperatures and damp, eventually decomposes the whole fruit into black meat and tastes sour。
(a) method of prevention: 75 per cent of methyl tobuzin was sprayed at the onset of the disease by over 90 per cent; two-effects of 250 times more effective than 85 per cent; 58 per cent of the vase manganese 800 times more effective。
The promotion of high-yielding fruit production, in addition to the control of flowers and porcelain fruit, requires fruit farmers to do well in pest and disease control, reduce the impact of pests and diseases on fruit production, promote high-quality fruit trees and increase the productivity of farmers。
