As agricultural technologies continue to develop, early spring shack cultivation has become an important means of improving the production and quality of agricultural products. The application of early spring production techniques can effectively lead to early marketing of vegetables, increase their production, improve their quality and generate greater economic benefits for farmers. This paper will present early spring production techniques from the selection of sheds, the selection of vegetable varieties, planting techniques, field management and pest control。
I. Selection of sheds
The first step in early spring shed cultivation is to choose the suitable shed. There are many types of sheds, such as small arch sheds, large shacks, etc. When choosing a shed, the choice needs to be based on the actual situation. In general, the arch sheds are suitable for growing crops such as vegetables and guacamole, while the shacks are suitable for growing higher value-added crops. At the same time, there is a need to take into account the temperature-preservative, photogenic and ventilation properties of the sheds。
Selection of vegetable varieties
The selection of vegetable varieties suitable for early spring sheds is crucial. In selecting varieties, factors such as climatic conditions, soil conditions and market demand need to be taken into account. In general, early spring temperatures are lower, and there is a need to select cold-resistant, pre-developed varieties. At the same time, factors such as vegetable production, quality and disease resistance need to be taken into account。
Iii. Cultivation techniques
Seeding: soil disinfection before seeding is required to reduce the occurrence of pests and diseases. At the same time, seeding needs to be determined according to the variety and growth characteristics of vegetables. In general, vegetables grown in early spring sheds require seeding in greenhouses。
2. Fertilization: the principle of proportionality is required in the application of fertilization, and too little affects the growth of vegetables. In general, the application of base-based fertilizers is required, and appropriate follow-up is required depending on the growth of vegetables。
3. Irrigation: the principle of proper and timely irrigation is needed to avoid causing soil slabs or water accumulation. At the same time, factors such as soil moisture and climatic conditions need to be taken into account。
4. Pest and pest control: pests and diseases are one of the major factors affecting the growth of vegetables. Integrated measures are needed to combat pests and diseases, including agricultural, biological and chemical control. Appropriate and timely principles are needed for chemical control to avoid pesticide residues and environmental pollution。
Iv. Field management
1. Temperature management: early spring temperatures are low, hence the need to keep the shed warm. It is necessary to maintain appropriate temperatures during the day and at night to protect against freezing at too low temperatures。
2. Humidity management: high humidity in the sheds, prone to disease. Therefore, there is a need for proper ventilation and reduced humidity. At the same time, there is a need to control the amount and frequency of water recharge to avoid causing soil overwetting or water accumulation。
3. Light management: lighting is one of the major factors in vegetable growth. While keeping the right temperature, there is a need to keep the vegetables as tan as much as possible and to facilitate light cooperation. At the same time, there is a need for the timely clean-up of dust and miscellaneous items on the large sheeting membranes to maintain good light。
4. Plantation adjustment: appropriate plant adjustment is required in the growing of vegetables, including measures such as twigs, heart breaks, etc., to promote crop growth and development. At the same time, there is a need for the timely clean-up of disease and weakness and the maintenance of clean and clean fields。
V. Pest management
1. Agriculture: effectively reducing the occurrence of pests and diseases can be achieved through sound agricultural management measures, such as crop rotation, intensive farming, etc. At the same time, the selection of highly resistant varieties is one of the important tools for agricultural control。
Biocontrol: the use of natural enemies and biological pesticides for pest control can effectively reduce the use of chemical pesticides and protect the ecological environment. For example, insect entrapment traps are used to induce insects to kill insects。
