Description

H-shaped pruning method for interplanting strawberries and melons
Technical Field
The invention relates to the field of horticultural plant cultivation, in particular to an H-shaped pruning method for interplanting strawberries and melons.
Background
The strawberry is a perennial herb of Rosaceae and strawberry, and is rich in amino acids, fructose, sucrose, glucose, citric acid, malic acid, pectin, carotene, vitamins B1 and B2, nicotinic acid, minerals such as calcium, magnesium, phosphorus, potassium and iron, etc., the nutrient elements have a good promoting effect on the growth and development of people, particularly contain a large amount of vitamin C, and the essence is the 'fruit queen' name. The strawberries are introduced into China for cultivation in the earliest 1915 years, and are rapidly developed after 80 years in the 20 th century, and the cultivation area reaches 533.33hm in the initial stage of 90 years in the 20 th century 2 . In recent years, the production of strawberries in China realizes the leap development, the cultivation area is multiplied and is more than 0.4 kilohm 2 World rank first.
The production period of the strawberries is short, the effect is fast, the income is high, and the development of the strawberry industry is the first choice of fruit growers in the current high-efficiency agricultural development process. However, as strawberries are planted in the greenhouse for many years continuously, successive cropping obstacles of the strawberries become serious day by day, and as the temperature rises rapidly in the middle and last ten days of the next 4 months, the strawberries become smaller, the yield is reduced, the sugar degree is reduced, and the price is greatly lowered, at the moment, most vegetable growers weaken management on the strawberries or directly pull the strawberries to fall into summer, so that the economic benefit of facilities and the harvesting of the peasants are greatly influenced. The muskmelon is used as a main horticultural crop for cultivation in early spring, and the cultivation area is up to 39.37 kilohm at present 2 However, the early spring cultivation of the melons is mainly realized in the form of single steel frame greenhouse multi-layer coverage, and the facility cost is highAnd continuous cropping obstacles are likely to occur. Therefore, a set of simple, efficient and feasible new cultivation mode for interplanting strawberries and melons becomes an urgent problem to be solved, and the method is also the most effective way for improving crop multiple cropping indexes, the cultivated land output rate and the land utilization rate and further realizing the efficiency improvement of strawberries and melons and the income increase of farmers.
In order to improve the multiple cropping index, fully utilize the early spring heat preservation effect of the facility and the space difference and the time difference of crop growth, carry out multi-level and multi-crop three-dimensional development, and reasonably arrange intercropping and interplanting crops and varieties, which is an effective way for further improving the economic benefit of growers and increasing the agricultural trip, an efficient planting mode for interplanting strawberries with melons, which has the advantages of low investment cost, simple management, high quality and high yield and remarkable benefit, needs to be found urgently.
