The current cotton has entered the bud period. It takes about 25-30 days for budding flowers to bloom. The bud period is a crucial period for shaping the ideal plant type. It is necessary to coordinate the contradiction between vegetative growth and reproductive growth. In this period, the management goal is to promote early bud emergence, multiple bud emergence, budding, early flowering, and establishment of a high-yield shelf. , to achieve a stable long-lasting, for the bell season more than the foundation of the bell. The following technical measures should be taken in the current management of cotton fields:
One, weeding weeding
During the bud period, the cultivator can play a role in inhibiting salt and protecting seedlings on the saline-alkali land, and it can warm up and promote the weak seedlings. For strong seedlings can play a certain role in control, bud stage 1-2 times, with shallow depth, the last time to reach 15-20 cm. To provide conditions for top dressing, at the same time with manual weed removal of cotton field weeds. Prosperous cotton fields can appropriately increase the depth of cultivating, while cutting off part of hair roots at the same time to control the growth and promote stability.
Second, timely transfer
Early sowing cotton plant height is generally about 30 cm, there are 8-9 leaves, 3-4 fruit branches, in order to prevent prosperous, we must do a good job of chemical control work. 3 days before spraying, spray desiccation amine is required. The dosage is divided into 10 plant heights and 30 kilograms of watered water (eg 25 grams of plant height 25 grams), spray once every 12 days; the late sowing cotton grows poorly and the internodes are short. With small leaves and small old seedlings already formed, it is necessary to promote the use of potassium dihydrogen phosphate (100 g/mu) and urea (150 g/mu) on the basis of irrigation and fertilization.
During the flowering period of cotton field, the top dressing was used for flowering and bolling, and the root development of cotton in drip irrigation cotton field was shallow, and the required nutrition was advanced. The cotton fields sown in the appropriate sowing period (April 10-25) are usually applied in the early stage of June when the base fertilizer is applied. According to the growth of the cotton, the fertilizer is applied 2-3 times with water, each time urea is dripped for 2-5 kilograms per mu. The amount of application was successively increased while potassium dihydrogen phosphate 1-1.5 kg was dripped. Conventional cotton fields (flooded land): Before the clay headwaters recover approximately 18-20 kg of urea per mu, the second water can be applied in small amounts according to the growth of the cotton; do not apply fertilizer before Sanshui to prevent prosperous growth; 12 kilograms, 5-8 kilograms before the second water; 7-8 kilograms before the sand water, 10-12 kilograms before the second water. Before Sanshui 5-6 kg. Using mechanical force, the depth of 10 -14 cm, about 15 cm from the seedlings, to reach the same depth, good covering, combined with top dressing potassium dihydrogen phosphate. The normal growth of cotton buds during the bud period of 50 mu of sulphur for foliar spray to reduce buds.
Dry sowing wet drip irrigation The first irrigation time of the drip irrigation cotton field is at the end of May or early June. The second irrigation time is mid June. The drip amount is about 20-25 cubic meters per acre, so that â€œthe big line can leave. Small rows see wet, the cycle of irrigation is 10-12 days (pay attention to prevent too much irrigation water overtime caused cotton leggy). The irrigation time of conventional cotton fields (flooded land) should be determined according to the characteristics of the water requirement of the cotton field in cotton fields and the flexibility of soil moisture. Mu irrigation volume is 40-50 cubic meters, do not flood the seedlings, do not drought seedlings, do not pour "running horse water", do not flood irrigation. At the same time, each village team should rationally arrange the order of irrigation, save water and ensure the quality of irrigation in the cotton fields.
V. Integrated control of pests and diseases
1. Cotton leafhoppers: At present, cotton leafhoppers have been moved into cotton fields. The method of "inserting, wiping, picking, pulling, painting, and striking" is adopted for prevention and control. For the cotton leaf mink must be controlled before the headwaters, prevention and control in accordance with the principle of "refusal to the field, blockade of the ground, picking a rule in the field, control the spot and prevent the spread". The first step is to insert the labeling work, the second step is to prepare the liquid and the third step is to carry out the operation: use the special acaricidal agent such as avermectin (1.8% schizophylline) 3000 times, 73% Ketel EC 2000 times, 20%, 1,000 times wolfberry EC, 5% Nisuo, etc. alternate spraying.
Remember to ask: find a strain to hit a circle, find a fight, use a large amount of water, low concentration of liquid spray uniform; on the corn trap on the concentrated control of red spider.
2. Cotton bollworm:
(1) For cotton fields surrounded by corn traps, use the habit of preferring to lay eggs in corn horns after the dawn of cotton bollworms. Every morning, fix a person to beat the corn heart and leaf to eliminate the trapped cotton bollworm adults. At the same time wipe eggs by hand, can reduce the number of insects and chemical control.
(2) The frequency-vibration type insect killer traps and kills adult cotton bollworm, and special personnel are responsible for switching lights and cleaning.
3. Cotton aphid: At present, there are cotton aphids in the cotton fields that harm the center strains. Although the harm is light, monitoring and investigation should be paid attention to in order to prevent large areas from occurring.
Horse Oil: History and Production
Before gaining popularity as a beauty product, horse oil was used as a [folk medicine" in the days of ancient China. Believed to be a remedy for burns, insect bites, cuts, asthma, foot fungus, and even hair loss, the miracle oil was supposedly first brought to Japan over 1,000 years ago. Because its properties are similar to the oils naturally produced by human skin, it is easily absorbed by the skin and is safe for people all ages, including infants. Due to its effectiveness as a moisturizing agent and anti-irritant, horse oil became especially popular in Hokkaido, as it protects the skin from the region`s harsh climate and cold, dry air. The vast expanse of land in the region made it easy to farm horses for the oil.
The product is made by extracting the oils from horse fat. Horses are regularly farmed and raised for their meat in Japan, which is served in the form of basashi (raw horse), so the animals are not slaughtered solely for the purpose of a skincare product. Rather, they are farmed for food, and their oil is a byproduct of this process.
