Technical Guide for planting Fruit and Maize

Technical Guide for Fruit and Maize planting:

Fruit corn is a kind of sweet corn suitable for eating raw.

Compared with ordinary sweet corn

Its main features are thin skin,

Juicy,

Crisp and sweet

You can eat it directly raw.

It can also be cooked and eaten.

Suitable for fresh food and processing quick-frozen or vacuum bags

. preparation before sowing

1.1

Land selection: the land should be good for drainage and irrigation, good uniformity, and high-medium soil fertility.

1.2

Set up a quarantine zone:

Because sweet corn is subjected to non-sweet corn flour will form non-sweet kernels.

So,

With

Different types of corn should be isolated from the land, around the sweet corn land.

Ordinary corn cannot be planted within rice.

There should also be a gap between strengthening sweet and super sweet corn.

Get rid of the chores.

Sweet corn seeds need not be soaked and are suitable for use.

Dry seed direct seeding, the emergence rate is high. Improper conditions or methods of seed soaking and accelerating germination will lead to a rapid decrease in germination rate.

1.5

Control of underground pests and rodents:

Sweet corn seeds are vulnerable to underground pests and rodents.

Sow the seeds at the same time

Draining water during the period of time.

The five-leaf stage is the period that determines the total number of leaves.

Enough water and fertilizer can increase the total number of leaves.

Root requirement of sweet corn

Large amount of oxygen

Loose soil is required.

Good ventilation.

Timely ploughing and loosening soil at seedling stage

Small cultivation of soil is to promote the vertical root system.

Important measures for deep stretching.

The application of potash fertilizer can also increase the moderate application of nitrogen fertilizer.

Phosphorus deficiency will lead to

Leading to baldness

Phosphorus is mainly supplied from base fertilizer.

The flowering stage is the sensitive period of sweet corn to water.

It is the period that needs the most water in the life, "the florescence is dry and the yield is reduced."

. timely harvest of fresh ears:

The green buds on the market are the ears of sweet corn from the end of milk ripening to wax ripening.

The index of the best harvest time is grain moisture.

70%

At this time the sweetness is high and the flavor is good. After harvest, there are more thick dregs, and the sweetness decreases. The ear of fresh fruit should be harvested.

Time processing

It should not be left overnight.

Otherwise the sweetness will decrease.

The flavor is poor.

Fresh fruit ears can be preserved in cold storage after quick freezing.

Over a long period of time, the market is supplied out of season.

six

. crop rotation:

Sweet corn is not suitable for continuous cropping. Reasonable crop rotation can reduce diseases and insect pests, reduce grass famine and restore soil fertility.
