First, cotton
Cotton: original drug (content 97%) usage and dosage:
1. Soaking seeds: generally use 1 gram per kilogram of cotton, add 8 kg of water, soak seeds for about 24 hours, remove and dry until the seed coat is white. Into the experience of no soaking, it is recommended to use 0.1-0.3 grams in the seedling stage (2-3 leaf stage), spray 15-20 kg water.
Function: Improve seed vigor, inhibit the elongation of hypocotyl, promote the growth of seedlings, improve stress resistance, and prevent high seedlings.
2. Bud stage: 0.5-1 g per acre, sprayed with 25-30 kg of water.
Role: Baogen strong seedlings, directional shaping, enhance drought resistance, sputum ability.
3, the initial flowering period: 2-3 grams per acre, sprayed with water 30-40 kg.
Function: inhibit the growth of cotton plants, shape the ideal plant type, optimize the canopy structure, delay the sealing and increase the number of high-quality bells, and simplify the mid-term pruning.
4, full flower period: 3-4 grams per acre, 40-50 kg water spray.
Role: inhibition of late ineffective branches and fangs growth, anti-greedy and late maturity, increase early autumn peaches, increase the weight of the bell.
The amount of wheat, rice, pepper, potato, and other crops per mu should not exceed 5 grams per mu to prevent phytotoxicity!
Second, wheat
Wheat is soaked with this product, the emergence time is advanced, and it is quick and tidy. It increases the tillering of individual plants and promotes root growth, which is beneficial to Miao Zhuang. The jointing period can increase the chlorophyll content of the leaves, which is beneficial to the improvement of photosynthesis, inhibiting the growth of stems, making the straws coarse, enhancing the lodging resistance and the development of nutrients to the reproductive system, and increasing the 1000-grain weight. Enhance stress resistance, drought resistance, and anti-caries ability to achieve high yield.
First, the use of the original drug:
1. Soaking seeds: use 4-5 grams, 2.5 kg of water, 5 kg of wheat, stir evenly, mix with the seeds, and dry to sown.
2, jointing period: 5 grams per acre, 50 kg water, spray.
3. Flowering period: 5 grams per acre, 50 kilograms of water, sprayed.
Second, the use of helper:
1. Soaking seeds: use 20 ml, 50 kg of water, 5 kg of wheat, and mix well.
2, jointing period: 20 ml per acre, sprayed with 50 kg of water.
3, flowering period: 20 ml per acre, sprayed with 50 kg of water, wheat should be used when paying attention to water and fertilizer conditions, water and fertilizer conditions are reduced.
Third, corn
Role: corn spraying ketamine or auxin can increase the permeability of the stratum corneum of the foliar, so that the plant is generally reduced, and the lodging resistance is enhanced. Significantly inhibit the vegetative growth of cornstalk. Promote reproductive growth, make the reproductive organs accumulate more organic nutrients, increase seed yield and single weight. After spraying, the leaves become shallower and deeper, which increases the chlorophyll content and enhances photosynthesis. It promotes the differentiation of small spikelets and has ripening effect. Reasonable use increased the average yield by more than 12%.
Usage: In the big bell period, use 5 grams of raw powder or 250g / L of water 20ml plus 50-60 kg of water, foliar spray.
Fourth, rice
Rice sprayed with ketamine or auxin can effectively reduce plant height and enhance lodging resistance. 1000-grain weight increased by 0.9-2.5 grams, and has ripening and drought resistance. In particular, long-term use of paclobutrazol area, season exchange use, the effect is better.
Flowering period: Spray with 5 grams of raw powder or 250g/L of water 20ml and 50-60kg of water.
Five, potato
After potato application of ketamine or auxin, the vine grows slowly, the vine is short and thick; the number of leaves is not reduced, but the petiole is shortened, which can control the distribution of vegetative growth, reduce the consumption of nutrients, and coordinate the growth of the ground and underground parts. The relationship shifts the photosynthetic product to the roots, increasing yield. The increase in production is 20-30%.
When the potato mash grows to about 80 cm (about the beginning of August), use 5 g of the original drug or 20 ml of the 250 g/L water agent per acre, and spray 50 kg with water to spray the seedlings.
Six, peanuts
The ketamine has the effect of adjusting the peanut, enhancing the contracting ability of light, improving the root activity of the peanut, strengthening the reproductive growth and increasing the yield and income. Appropriate application, the increase rate is generally 15-30%.
The application method can be used three times in the soaking, initial flowering and full flowering stages, and the field of the general water and fertilizer conditions can be sprayed once at the flowering needle and once in the initial stage of the pod. Use 5 grams of raw powder or 20 ml of 250 g / L water, and spray 50 kg with water. For the vigorously growing fields, spray each time during the initial flowering and flowering periods. However, the amount of per mu should not exceed 3 grams or 14 ml of 250 g / L of water. Pay attention to topdressing and watering to prevent premature aging caused by lack of fertilizer and less water, which will affect the use effect.
Eight, chili
The use of ketamine or mepiquat can regulate growth and development well on peppers, inhibit stem elongation and increase the number of side branches. In particular, the effect of preventing falling flowers, falling buds and fruit preservation is obvious, and the yield increase is about 20%.
Spray 5 g of raw powder per acre or 20 ml of 250 g/L of water at the beginning of flowering.
Nine, tomatoes
The use of ketamine or auxin on tomatoes can control the shape of the plants, reduce the height, increase the thickness of the stems, reduce the axillary buds, promote the early flowering of the tomatoes, and produce more results; reduce the falling flowers, drop the fruits, harvest in advance, is the current tomato Key measures for high yield cultivation. After 20 days of transplanting, the leaf is sprayed at the three-leaf stage, and the drip is formed when spraying. The original powder of 3 grams or 250 ml of water is 12 ml, and the water is about 50 kg; Initial flowering period: use 5 grams of raw powder or 20 milligrams of 250g/L water, and spray about 50 kilograms of water.
Ten, grapes
Spraying statin or melanin during the flowering period of the grape can shorten the grape branches. The sound of the leaves becomes darker, the fruit is large and tidy, the maturity is earlier, the sweetness is increased, and the yield increase effect is above 20%.
Before the flowering of the grapes, spray 5 grams of raw powder or 250g/L of 20ml.
Spray once in the expansion period of young fruit, use 5 grams of raw powder per mu or 250g/L of 20ml of auxin. There are many varieties of grapes. Different varieties have different sensitivity to this product, and should be treated differently.
Eleven, Apple
This product is mainly absorbed by the leaves and roots of fruit trees, which can inhibit cell elongation and increase the absorption of calcium ions. The leaves and rhizomes of the fruit are prolonged and the core is reduced.
According to the growth characteristics of apples, in the first ten days of July (the summer shoots have sprouted), spraying 5 grams of raw powder or 250g/L of 20 ml of auxin, the chlorophyll of the leaves can be increased, and the internodes become shorter, which promotes branching. And the role of axillary buds. According to the trend of rainfall and length: in early September, spray again according to the above dosage.
