Changing the planting mode to improve economic efficiency
Water control fertilizer
In the transformed apple tree, the ability of its roots to absorb water and nutrients is not greatly affected in the initial stage of growth, but the excess of nutrients is relatively surplus due to the elimination of a certain amount of branches in the tree body. Therefore, in order to prevent the trees from prospering and prosperous, they do not encounter particularly arid conditions. Generally, they do not need watering. At the same time, they must strictly control the amount of fertilizers, especially nitrogen, and the strong trees should be dominated by organic fertilizers.
The cultivation mode of autumn celery + spring cucumber has been used for more than ten years in Funan County, but the benefit of this planting structure is obviously low. The cucumber in spring is limited by the shed, in the cold winter and spring seasons, the growth is slow, and the yield is low; while the autumn planting vegetables, especially the celery, lettuce and other economic benefits are lower. Together, the gross income of the sheds in one mu of land is less than 20,000 yuan.
For this reason, the author proposes to change the cultivation mode of cucumber + autumn celery in spring:
One, spring cucumber + autumn cucumber
Keep the original main spring cucumber, change autumn celery autumn cucumber. The reason is as follows:
1. Cucumber is one of the main vegetables in the market, its economic benefit is significantly higher than celery, lettuce and so on.
2. Although autumn cucumbers and local cucumbers collide with the open-air autumn cucumbers, the greenhouse cultivation has a fast growth rate, high yield, and is affected by the weather. Diseases, insects and weeds are light and the quality is good.
The autumn cucumber is planted in the middle and late August, and it is pulled before and after New Year's Day. The main points of management are: preventing high temperature in the early stage, avoiding plants from prolonged growth, and preventing premature senescence in the medium term; timely flushing and maintaining good harvest; late-stage low-temperature control and extension of the melon period.
Second, multi-cultivation cultivation
By using Shouguang, Qingzhou, Changle and other arch shed cultivation models, on the basis of retaining spring sorghum cucumbers, sorghum can be added, planting varieties can be increased, and the status quo of a single plant variety and low benefit can be avoided.
It can be changed to the mode of "Spring Cucumber + Tomatoes in Summer (Soybeans, Spinach) + Autumn Amaranth." Make full use of the time and space in the shed, make a difference in time, and increase the number of summers.
For summer tomatoes, choose high-temperature red fruits such as Gabriel or pink fruit Congo, plant in the middle and late May, and leave 4-5 fruit topping. The key points of management are: anti-high temperature, pest control, anti-virus, and anti-dropping fruit.
Over summer spinach, choose 398, K7 and other varieties with high temperature resistance. The more summer spinach, the faster the growth, generally 25 to 30 days can be harvested, can use the advantages of shelter rain, grab the time to plant 2 to 3 spinach.
Doctor's necessary facilities, doctor's water system, storage equipment space, computer integration function, lighting assistance, masks, gloves, paper towels, protective equipment storage.
The surface is resistant to high temperature, corrosion, various textures can be selected, and various sizes and configurations can be customized. Stone table top, solid, smooth and durable.
