Embodiment 1

[0024] The test site is located in Zhoufang Village, Dongcheng Town, Danzhou City, Hainan Province. The soil pH is 5.18, the organic matter content is 12.51g / kg, the alkaline nitrogen is 95.46mg / kg, the available phosphorus is 82.60mg / kg, and the available potassium is 42.10mg / kg. The crop is rice.

[0025] The experiment was set up with 4 treatments

[0026] Treatment 1: Pepper single cropping (ridge width 70cm, double-row planting, row spacing 50cm, plant spacing 30cm, about 3300 plants per mu).

[0027] Treatment 2: 2 rows of lettuce intercropped with 2 rows of peppers (peppers are planted in double rows, ridge width 70cm, row spacing 50cm, plant spacing 30cm, planting about 3300 plants per mu; lettuce planting spacing 15cm, both sides are planted parallel to 2 rows of peppers).

[0028] Treatment 3: 1 row of lettuce intercropped with 2 rows of peppers (planted in two rows of peppers, ridge width 70cm, row spacing 50cm, plant spacing 30cm, planting about 3300 plants per mu...

Abstract

The invention relates to an intercropping method of leaf lettuce and peppers. The intercropping method comprises the steps of land selection and preparation, leaf lettuce seedling cultivation and pepper seedling cultivation, and specifically comprises the steps of variety selection, seed processing, seed germination accelerating, sowing, field planting, nutrient management, disease and pest control and the like. The intercropping method of leaf lettuce and peppers is adopted, so that the utilization rate of soil and the income of farmers can be increased by utilizing the idle time before peppers are harvested, the mutual action relation of the leaf lettuce and pepper root secretion can be utilized, and the occurrence of soil-borne diseases is reduced; meanwhile, weeds in a pepper field areeffectively inhibited, light, heat, water and soil resources are effectively utilized, rich planting of the space of the pepper field is promoted, and leaf type vegetable supply and the income of thefarmers are increased under the condition that pepper planting is not influenced.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for intercropping lettuce and pepper. Background technique [0002] Lettuce is a sharp-leaf lettuce with young shoots and leaves as its products. It has high nutritional content, contains a lot of vitamin A, vitamin B1, vitamin B2 and a lot of calcium, iron and other nutrients. Very tender, fragrant, with a unique flavor, it is the top grade among raw vegetables. At the same time, it has the characteristics of heat resistance, cold resistance, strong adaptability, humidity, resistance to diseases and insect pests, and a suitable growth temperature of about 25°C, which is very suitable for winter and spring growth in Hainan. At present, heat-resistant and disease-resistant varieties suitable for Hainan have been successfully selected. Hainan's winter vegetables are mainly planted with solanaceous fruits, beans and melons, which are mainly transported from ...
