What are the precautions for cassava planting?

Introducing the different periods of cassava cultivation:

Seedling stage. At temperatures above 21 °C, cassava can germinate 7-10 days after planting, and seedlings are seedlings 60 days after planting.

Time limit. It is the most prosperous period of young roots in the growth process, but the plant grows slowly during this period, and the nutrients required in the early stage of seedling growth are mainly stored by the nutrients stored in the stems**, the fresh and robust hair roots of the stems are more, the elongation is fast, and the root system is developed, but the number of roots is not significantly related to the number of tubers.

Tuber root formation period.

60-100 days after planting is the root formation period, of which 70-90

The day is the peak season for potato production. After 90 days of planting, the number and length of tuber roots have been basically stable, each plant usually has 5-9, at this time the stem and leaf growth is more rapid, the plant height can reach more than 1 meter, and the first apical branch begins to appear, the amount of stems and leaves is about 3-4 times that of the seedling stage.

In addition to the characteristics of the variety, the early and late formation and quantity of tuber roots are also closely related to water and fertilizer and soil environment. During the root formation period, if the soil is compacted or severely drought and fertilizer is deficient, the number of tubers and the yield will be reduced.

Tuber root swelling stage.

In production, the growth process from the block period to the harvest is called the block.

Root swelling phase. At this time, the growth of stems and leaves is very large, and the leaf volume reaches the highest peak of the whole growth period, after which the leaves begin to fall off, and after October, the thickening of the tubers slows down, and by the end of November, a large number of leaves fall off, and the tuber basically stops thickening.

Root maturity.

Generally, 9-10 months after planting, the tuber root has been fully expanded, the aboveground part almost stops growing, most of the leaves fall off, the tuber root basically stops thickening, and the water content decreases.

One is according to the climatic characteristics and the quality of the land, the method of cutting stems is adopted, the other is to carry out ditch planting on flat land, digging holes for planting, can also be bred with stems, and can also bury tubers directly into the soil, or directly planted with machines.

It can be planted by machine, by manual sowing, by soilless culture, by hydroponics, or by planting in pots, which are all more common planting methods.

You can choose flat or oblique insertion, in the process of planting to cut off the stems with a knife, choose a piece of relatively fertile land for field management, but also timely watering, top dressing spraying pesticides.

You can choose flat or straight insertion, oblique insertion, flat insertion and other methods, choose some high-yielding, can prevent diseases and insects, after planting, usually to avoid some heavy rain.

You can choose the way of rhizome planting, you can choose seeds for planting, you can choose transplantation method for planting, you can choose to lay flat, straight insertion, oblique insertion.

How cassava is grown.

1. Seed selection. Depending on the region, it is important to choose cassava varieties that are suitable for the local environment so that they can grow better. At the same time, the selection of cassava varieties should be selected with relatively large tubers and no surface damage or decay.

2. Land preparation. Cassava has strong adaptability, the requirements for soil conditions are not strict, in plains, mountains, wasteland, sandy, loam, clay can be planted, however, when preparing the land, the soil should be finer, and then make ridges and furrows, and apply good base fertilizer.

3. Planting. There are three methods of cassava planting, namely flat placement, oblique insertion and straight insertion, and the suitable planting method can be selected according to different terrain, soil, environment and temperature. At the same time, when planting, plant the tubers or seeds well and cover them with a thin layer of soil.

4. Management. After the cassava is planted, if it is found that there are no seedlings, the seedlings should be replenished in time, and then the planting should be carried out. After planting, when it grows new roots and leaves, it is necessary to weed, weeded every once in a while, and apply fertilizer when the cassava is about to bear fruit to promote the growth of cassava, the general fertilizer used is urea, potassium chloride and nitrogen fertilizer, which can make the roots grow and accumulate more starch.

The time when cassava was planted.

Cassava is generally planted in February-April every year, with slightly different times in different regions.

The method and time of cassava cultivation are described as follows:

1. Planting method: choose suitable and healthy varieties according to the local soil and climate. After fertilizing the land, plant reasonably and control the spacing between plants. When the plant grows 3-5 true leaves, transplant it, and scientifically fertilize and water it after transplanting survives, so as to prevent and control pests and diseases in time.

Choose the land with sufficient sunshine, deep soil layer and good drainage, plant after the land preparation is applied with sufficient base fertilizer, supplement the seedlings after emergence, and survive the calibration, combined with fertilization, weeding and weeding, and weeding is required three times and topdressing twice during the growth period. It is okay to plant cassava with or without pruning, and it may be that pruning can make cassava grow better for cassava, so you can prune it when planting cassava.

Of course, if you don't want to prune, there is no problem, but the growth of cassava may be a little slower, not as fast as that of pruning.

2. Planting time: from February to April every year, there are certain differences in different regions. It is harvested around November and December, and the whole growth period takes more than 300 days. Cassava needs to grow in more than 15 years, otherwise it is not conducive to survival.

Preparation of cassava:

1. Fried cassava.

Fresh cassava can be fried and eaten, when frying, you need to wash the fresh cassava, cut off the skin and cut it into long strips, prepare an appropriate amount of starch and an appropriate amount of water to make a paste, dip the cut cassava fries in starch water, put an appropriate amount of cooking oil in the pot, bring it to heat, put the cassava fries directly in the hot oil, fry until the surface is slightly yellow, take out the drain oil after frying, and you can eat it after cooling.

2. Tapioca syrup.

Cassava can also be made into sugar water to drink, when you make it, you need to prepare 250 grams of fresh cassava to wash it, then peel off the skin and cut it into small pieces, and then prepare an appropriate amount of sugar, put them together in a rice cooker, add an appropriate amount of water to heat and boil and then cook for about 20 minutes, cut off the power after cooking, and take it out to eat after cooling.

3. Stir-fry cassava.

Tapioca fried taste is also very good, when you do it, you can prepare a piece of ham, cut it into slices, and then peel the prepared fresh cassava and cut it into slices and put cooking oil in the wok, put an appropriate amount of green onion and fry it until it is fragrant, and then quickly stir-fry the cassava and ham together, put a small amount of light soy sauce, add edible salt to taste, continue to fry for three minutes, and fry until the cassava is cooked through and directly out of the pot.

<>1. Land consolidation: plough the land about 30 days before planting, and apply 500-750kg of farm fertilizer, 15-25kg compound fertilizer and 25kg phosphate fertilizer in combination with land consolidation. 2. Transplanting:

It is planted from February to April every year, with a row spacing of about 100 80cm or 100 100cm, and 600-1000 plants are transplanted per mu. 3. Management: 40-60 days after transplanting, apply urea and 5-7kg potassium fertilizer per mu.

From May to July, 10kg of urea and 15kg of potassium fertilizer were applied per mu. From September to October, 5-7kg of potassium sulfate was applied per mu.

1. Land consolidation

1. Choose flat land or gentle slope land with good drainage conditions, and plough about 30 days before planting, with a depth of about 30-40cm to ensure that the land is flat and loose.

2. Apply 500-750kg of well-decomposed high-quality farm fertilizer, 15-25kg compound fertilizer and 25kg of phosphate fertilizer as base fertilizer per mu.

2. Planting

1. Cassava is generally planted from February to April.

2. Select the main stem with a stem diameter of about 2-4cm, no damage, no disease or pest damage to the dense nodes, stem bark and bud eyes, and fully mature, then remove the upper part of the main stem, keep the middle and lower stems, and prune them to 15-20cm.

3. The planting is divided into four planting methods: flat placement, oblique insertion, straight insertion and flat insertion, and the direction of the bud eye is required to be unified.

4. The planting row spacing is controlled at 100 80cm or 100 100cm, and 600-1000 plants are transplanted per mu (if it is a cassava variety with relatively fertile soil or strong branching ability, it should be planted appropriately, and if it is a poor soil fertility or the cultivar is an upright variety, it should be planted densely).

3. Management

1. Complete the seedling replenishment work as soon as possible within 20-30 days after transplanting, and after the seedlings are full, the seedlings grow to about 15-20cm, and 1-2 plants are retained in each planting hole.

2. About 30-40 days after transplanting, when the seedlings grow to 15-20cm, the first tillage and weeding will be carried out. About 60-70 days after transplanting, the second tillage and weeding are carried out. Around 90-100 days after transplanting, the third tillage and weeding are carried out.

3. About 40-60 days after transplanting, when the seedlings grow to 20-30cm, urea and 5-7kg potassium fertilizer are applied per mu. From May to July, when the plant grows to 60-90cm, 10kg of urea and 15kg of potassium fertilizer are applied per mu. From September to October, when the plant grows to 100-130cm, 5-7kg of potassium sulfate or potassium chloride per mu is applied.

4. For cassava seedlings that are too vigorous, when the plant height is 30-50cm, 80-100cm, and 130-150cm, two packets of paclobutrazol and 50g potassium dihydrogen phosphate are diluted with 15kg of water, and sprayed on the top of the plant and the tender parts, so that it is advisable to apply without water droplets.
