Fertilizer and water integrated high-yield cultivation method for early-spring watermelons and autumn delayed chilies in greenhouse

Abstract

The invention discloses a fertilizer and water integrated high-yield cultivation method for early-spring watermelons and autumn delayed chilies in a greenhouse. The cultivation method specifically comprises the steps of preparation of seedling beds for watermelons and chilies, seed soaking and germination acceleration, sowing, land preparation and bed making, field transplanting, a seeding recovery stage, a flowering and fruit bearing stage, a maturation stage and a harvesting stage. According to the fertilizer and water integrated high-yield cultivation method for early-spring watermelons and autumn delayed chilies in the greenhouse, the temperature, the humidity and the fertilizer and water amount are strictly controlled according to the growth features of watermelons and chilies, watermelons and chilies grow vigorously, the mu yield of watermelons ranges from 3500 kg to 4000 kg, the mu yield of chilies ranges from 2900 kg to 3100 kg, and watermelons and chilies are uniform in size, bright in color, pure in taste and rich in nutrition; chilies are planted after watermelons are harvested, and alternation planting is achieved; watermelon vines are smashed and then scattered into soil, soil fertility is ensured, and pathogen microorganisms are suppressed; a fertilizer and water integrated pipe network conforms to the planting density of watermelons and chilies and only needs to be arranged one time, materials are saved, the utilization rate is increased, the production cost is reduced, and the economic income is increased.

Description

technical field [0001] The invention relates to the field of crop planting, in particular to a high-yield cultivation method for the integration of fertilizer and water for early spring watermelon in a greenhouse and pepper in late autumn. Background technique [0002] Watermelon has a well-developed root system, wide and deep distribution, strong ability to absorb water and fertilizer, early wood tethering, poor regeneration ability, and aerobic. Stems trailing, hollow. It likes temperature and heat resistance, likes light, likes humidity and drought resistance, but does not tolerate waterlogging. Under the conditions of day temperature of 25~30℃ and night temperature of 17~20℃, melon flower bud quality is high, flower bud is large and firm, ovary is well developed, and fruit setting rate is good. high. [0003] Capsicum belongs to Solanaceae Capsicum genus, and is a solanaceous vegetable. The plant consists of underdeveloped roots, stems, leaves and roots, with few roots...

Problems solved by technology

[0004] In the conventional cultivation of early spring watermelon and autumn pepper in greenhouses, nutrient pots are often used for seedling cultivation, furrow irrigation or flood irrigation is used for irrigation, and fertilizer topdressing is applied by spreading, which often results in the loss and waste of fertilizer and water, which cannot be used in different growth stages of crops.
