The invention discloses a light and simple cotton cultivation method suitable for the Dongting Lake cotton area, which is specifically realized through variety selection, sowing time, planting density, fertilization, pest and weed prevention and control, topping, chemical ripening, and harvesting. The method of the invention greatly reduces the management time and labor of the cotton field, and not only increases the cotton planting density to achieve high yield, but also reduces the number of holes in the cotton field to ensure ventilation and light transmission in the field, prevent boll mold and rot, and ensure the quality of cotton.

The invention discloses an ultrahigh yield cultivation method for the cotton canopy design and application of the ultrahigh yield cultivation method. The method includes the following steps of firstly, delaying topping, wherein the topping time of cotton is delayed for 4 days to 5 days; secondly, completely conducting capping and fertilizing, wherein capping and fertilizing are completed in ten days after topping is conducted; thirdly, appropriately conducting chemical control at the right moment, wherein chemical regulation and control are conducted twice after topping is conducted, chemical regulation and control are conducted for the first time 2 to 3 days after topping is conducted, and chemical regulation and control are conducted for the second time 5 days to 7 days after chemical regulation and control are conducted for the first time; fourthly, prolonging insect control time, wherein the insect control time is prolonged to 20 days to 25 days. By taking comprehensive measures of appropriately delaying the topping time, completely conducting capping and fertilizing, appropriately conducting chemical control at the right moment, delaying the insect control ending time and the like, and by fully using the characteristic that temperature and photothermal resources on the top of cotton are rich, the yield-increasing potential of cotton is tapped, and the per unit area yield of cotton is increased by more than 15% compared with an existing cultivation method.

The invention discloses a method for conducting wild tending of Chinese Paris rhizome under trees. The method is based on the planting principle of in-situ conversion, nearby development, wild tending and guaranteeing quality. For wild tending of Chinese Paris rhizome, a special traditional Chinese medicinal material cultivation medium suitable for growth of Chinese Paris rhizome and disease control is selected and applied, and a cultivation method comprising the steps of soil condition improving, land selection and preparation, reproduction, field management, disease and pest control, topping and harvesting is established. When the method for conducting wild tending of Chinese Paris rhizome under trees is used for cultivation of Chinese Paris rhizome, growth of roots and stems of Chinese Paris rhizome can be promoted, the incidence of diseases is reduced, the quality of the roots and the stems is improved, and the harvest yield is increased; the method can be used as a standard cultivation method for wild tending of Chinese Paris rhizome and has good development prospect.

The invention relates to the field of agricultural technology, in particular to a topping-free cultivation method for machine-picked cotton based on the precise operation of metrendamine and water and fertilizer, based on the high-efficiency application of metrendamine and the precise operation of water and fertilizer, so as to achieve the cultivation of machine-picked cotton In the process, the goal of no topping is achieved, neither manual operation nor application of special chemical capping agent is required. Moreover, the economic output is equivalent to the current artificial topping cotton field and chemical topping cotton field, and the cost saving is 43-45 yuan / mu. The method achieves the effects of promoting the growth of cotton plants, reducing labor and labor intensity, improving topping efficiency, reducing topping costs, and increasing output through the above method, and can replace manual topping to realize the mechanization of the whole process of cotton production.

The invention provides a method for cultivating a dragon fruit fattening stock on trees, which includes five steps: selection of new shoots, thorn base removal, fixed-length topping, tree fattening and fattening stock harvesting, and has the advantages of simple operation, high efficiency, convenience, and survival. It has the characteristics of high rate and good quality of the "finished fattening anvil" produced. The dragon fruit fattening stock cultivation method of the present invention utilizes the nutrient supply and wound self-healing ability of the plant mother itself, and completes castration, healing, fattening, etc. The whole process of cultivation is used to produce fattening stock, which can effectively solve the problems of high wound infection rate and long fattening time caused by the common in vitro rooting and fattening method during the implementation process.

The invention relates to the field of greenhouse watermelon cultivation, and particularly relates to a non-specific regional early-ripening promotion cultivation technology for small-fruit watermelonsspecial for facilities. The water channel can be formed at the concave part in the middle of the ridge through the shape ridge, so that the watering is carried out conveniently, the water can be ensured to permeate to the periphery of the root system, and the water utilization rate is improved; after planting, the black-white metachromatic film can effectively shorten the seedling delay time of the seedlings until the seedlings break the film; the vegetative growth period of the melons can be shortened through the two-layer arched shed; the number of seedlings planted per mu can be increasedthrough the V-shaped hanging vine, so that reasonable close planting is achieved; the double-topping technology is adopted, the topping is carried out for the first time, and the formation of lateralbranches of effective results is promoted; the secondary topping is carried out after the fruit is seated and the melon vine grows to the position where the melon vine hangs the iron wire, so that thegrowth of the melon vine can be controlled; when being used as a picking item, a non-woven fabric mulching film is laid between planting rows, so that tourists can view and pick conveniently among rows. According to the method to plant the extremely early- ripening small-fruit watermelons, about 1500 seedlings can be planted in each mu, and 150 plants are more than those of the traditional small-fruit watermelons, so that the space is fully utilized, and reasonable close planting is achieved.
