Planting method of strawberry corn

Planting method: strawberry corn is suitable to be planted from the end of March to the beginning of August, the sandy loam field with fertile and good drainage can be selected, and the planting density is about 3500-4000 plants per mu. Scientific fertilization: during the growth period, basal fertilizer, early seedling fertilizer, panicle fertilizer can be applied, nitrogen, phosphorus and potassium can be applied, and organic fertilizer can be applied appropriately. Fine management: it is necessary to do a good job in field management, timely check seedlings, replenish seedlings, control weeds, and pay attention to the control of corn borer and other diseases and pests in the later stage.

I. planting by stages

The main results are as follows: 1. In order to avoid the decline of quality caused by flower strings, strawberry corn should be isolated from other varieties of corn, and can be isolated by hills, forests, houses and other barriers. Strawberry corn harvest period and preservation period is short, planting in stages can be harvested in batches and listed on the market.

2. Generally, plants can be planted from the end of March to early August, and those with thermal insulation facilities in early spring can be planted in advance, but it is necessary to avoid planting between late May and mid-June, when strawberry corn is planted during the flowering and pollination period. it happens to meet the summer drought in July-August, which can easily lead to bald tip, lack of grains and empty stalks.

Second, accelerating budding and transplanting

1. Strawberry corn seeds are wrinkled and the endosperm is small, so the germination rate is low and the seedling potential is weak. In order to ensure that the seedlings are whole, complete and strong, no matter they choose direct seeding or seedling planting, they all need to accelerate germination. The suitable temperature for germination is 20 ℃-25 ℃. They can be sown in spring and summer, cover the soil about 2cm after sowing, then water them and wait for 8-12 days to emerge and transplant.

2. Suitable for planting in sandy loam with sufficient fertilizer and water and good drainage, strawberry corn has flat leaves and loose plant type, and the planting density is 3500-4000 plants per mu. Strawberry corn is not resistant to cold and avoid heat, and the suitable temperature for growth is 20 ℃-30 ℃. Watering should be carried out properly during flowering to prevent strawberry corn from lodging and fine ploughing the soil before planting strawberry corn.

III. Scientific fertilization

When planting, it should be suitable to apply base fertilizer, early seedling fertilizer and heavy ear fertilizer, during which nitrogen, phosphorus and potassium can be applied together, and organic fertilizer can be properly increased to be planted in fields with medium fertility. the total amount of chemical fertilizer should be controlled at about 30 jin of pure nitrogen, 12 jin of phosphorus pentoxide and 12 jin of potassium oxide.

IV. fine management

Strawberry corn grows weakly in the seedling stage and is vulnerable to diseases and insect pests in the later stage, so it is necessary to do a good job in field management in time, check seedlings, replenish seedlings, control weeds in time after emergence, remove tillers in seedling stage and middle stage, and have extra small ears. In the middle and later stages, it is necessary to control diseases and pests such as corn borer, the harvest time of strawberry corn is about 3 days earlier than that of ordinary sweet corn, and about 20 days after strawberry corn is pollinated, according to the color of filaments. Harvest in time.
