Peas are cultivated in all seasons, choosing the right variety is very important

1. Seed selection

If you want to grow peas in all seasons, it is very important to select the right varieties. After years of experimentation by experts, two varieties, Zhongwan 6 and Zhongwan 4, have been selected, supplemented by greenhouses and other facilities for four-season cultivation of peas.

Second, timely sowing

According to experimental demonstrations and production practices, in the lower reaches of the Yangtze River, the relationship between the sowing period and the harvest time is as follows: Autumn shade net shed cultivation in early August-end of August before October 1st, autumn open field cultivation in late August-mid-September October In the middle, winter film greenhouse cultivation October-New Year's Day in February of the following year, winter open field cultivation November-January of the following year around May 1, spring open field cultivation February-April mid-May, summer open field cultivation in May Early-May and late June, summer shade net canopy cultivation in mid-May-June mid-June and early July.

Three, reasonable close planting

Zhongwan No. 4 and No. 6 are dwarf varieties with a plant height of 40-50cm, and should be planted appropriately. In spring, summer and autumn, the row spacing is 35cm, the hole spacing is 10cm, and each hole is 3 grains. The seed quantity of 667 square meters is about 10kg. The row spacing of winter sowing is 40cm, the hole spacing is 15cm, 3 seeds per hole, and the seed weight of 667 square meters is about 7kg.

Four, fertilizer and water management

Choose a field with good soil fertility, convenient irrigation and drainage, and sufficient sunlight for planting. Apply 30-40kg of nitrogen, phosphorus, and potassium compound fertilizer for 667 square meters as base fertilizer, and apply a certain amount of organic fertilizer. Apply 10kg of urea or 1000kg of human and livestock fertilizer to 667 square meters in the flowering and pod stage to promote pod setting and strong seeds.

In the later stage of growth, a mixture of 0.5% urea solution and 0.2% potassium dihydrogen phosphate can also be used for extra-root fertilization according to growth. Water in time during drought, especially when the plants are particularly sensitive to water during the flowering and pod setting period, so add water in time. In addition, peas cultivated in summer should pay more attention to the timely supply of water, so that it can not only meet the water demand for plant growth and development, but also effectively reduce the surface temperature and promote its normal growth.

5. Timely application of protection facilities

1. Among the anti-freezing measures, No. 4 and No. 6 have strong anti-freezing ability in the seedling stage, but the anti-freezing ability declines sharply after flowering, and the pod needs a certain temperature during the long-grain filling stage. Therefore, it is necessary to cultivate peas in a greenhouse in winter Buckle and cover the plastic film, and do a good job of cold protection and heat preservation. Before the short-term strong cold current comes, you should temporarily cover with cold protection materials to protect the young green peas from freezing damage.

2. Sun-shading and cooling measures. Summer cultivation is due to the high temperature, fast growth, short growth period, and small and few pods. Therefore, the sunshade net should be covered at the right time to effectively reduce the direct sunlight, which can reduce the air temperature and ground temperature, increase the soil humidity, and promote The growth of individual plants increases yield.

Six, timely harvest

Due to the different growing seasons and cultivation methods, the number of days from flowering to harvesting of green bean pods varies greatly. In summer cultivation, due to the high temperature and rapid growth of the bean pods, only 20 days from flowering to harvest, while in winter cultivation, it takes from flowering to harvest. More than 30 days, therefore, we need to flexibly control the harvest date according to the purpose of the pod and the strength of the pod. For those who eat green peas, the pods are fully swollen, and the beans are 70% full. The pods are harvested when they just start to turn color.
